Essays About Biology: Top 5 Best Examples and 6 Prompts

Writing essays about biology can be difficult because it’s composed of many subtopics. Check out this article for our top essay examples and writing prompts.

Biology came from the Greek words “bios” (life) and “logos” (study). It’s why biology is the study of life or living organisms. Aside from being a natural science, it also has consolidated themes, such as cells making all organisms. Because it’s a broad topic, biology is divided into specialized fields such as botany, genetics, zoology, microbiology, medicine, and ecology. 

Biologists consider living beings’ origin, evolution, growth, function, structure, and distribution. It’s a comprehensive subject, so there are many things you can write about in your essay. However, at the same time, you might find it challenging to focus on just one area. 

Below are examples to give you an idea of how to write your essays about biology:

1. Essay About Biology by Kelli Wilkins

2. my interests in biology by anonymous on essaywriting.expert, 3. essay on the importance of study of biology by akhila mol, 4. what biology means to me by anonymous on studymode.com, 5. how my biology teacher changed my perspective of learning the subject by sankalan bhattacharya, 1. biology in my everyday life, 2. something i realized because of biology, 3. my memorable biology class experience, 4. genetics’ role in people’s diseases, 5. my experience during the pandemic, 6. biology and health.

“Studying Biology is important for a number of reasons, but in particular because it is used in every field. If we did not have a good understanding of Biology then nobody would be able to understand how bodies work, and how life on earth functions.”

Wilkins shares her desire to study anatomy, a branch of biology, and expounds on what makes biology an essential field. Because biology lets people know more about the world, she digs into why she’s interested in anatomy, specifically to find ways to cure illnesses and develop technologies to discover new treatments. She ends her essay by relating biology to the existence of doctors and hospitals. 

“It is known that education plays an important role in the life of any individual. It gives an opportunity to develop personality and gain specific skills, to get profound knowledge and experience in order to apply them practically in the future. As for me, my major goal is to study Biology in order to get appropriate knowledge and skills required for my future profession.”

The author shares why they want to study biology, referring to the human body as the “perfect machine” and curious about how it performs each of its systems’ functions. The writer also mentions how biology is critical to their future profession. They aim to help people with their health problems and relay their desire to research the brain to find more data on it. 

“The study of biology owes great significance in human life, because man for its day-to-day requirements is dependent on plants and animals either directly or indirectly.”

Mol lists seven reasons why humans need biology in their daily lives. Her list includes health, diseases, agriculture, horticulture, food, animal breeding, and entertainment. She expounds on each point and how they affect a man during his time on Earth. She explains each relationship in a simple manner that’s easy to understand for the readers.

“Without biology, we would have no idea about an organism’s makeup, or the most basic unit of life, a cell… Biology influences me in many ways. Biology influences me by teaching me why to take care of the environment, why I am to take care of my body, and by giving me a better overall view of all scientific areas of study.”

In this short essay, the writer lists down reasons why biology is essential. These reasons include taking care of the environment, one’s body, and others. The author also expounds on their reasons by presenting facts supporting biology’s importance to the world and human lives.

“He told that the syllabus may be a good way to prepare for an exam but our knowledge should not be limited to any syllabus and the questions that were asked in the examination were related to the topic only. He told that if we try to know things in detail and understand them properly then the interest in the subject will develop, otherwise, students will not treat the subject as a subject of their choice. 

Bhattacharya shares his experience with a teacher with a unique teaching style. His Biology teacher from Class 7, before the era of the internet, don’t just carry one book to get all his lessons from. Instead, he has a notebook with the collated information from many books to teach his class. 

Bhattacharya’s teacher taught them things that were not in the curriculum, even if following the curriculum would give him higher points in his evaluation. He only wanted his students to learn more and share with them why learning differs from just knowing.

6 Prompts for Essays About Biology

You don’t have to be a biology student to write an essay about the subject. If you’re looking for easy prompts to write about, here are some to get you started:

If mitochondria are the powerhouse of the cell, who is the powerhouse of your classroom? Your home? Relate a biology topic to a similar structure in your life, then explain why you think they are the same. 

For instance, you can compare your mother to mitochondria which generate the energy needed to power a cell. The cell being you. You can say that she gives you energy every day by being there and supporting you in whatever way she can. This prompt bodes for a creative and intriguing essay.

Relay a lesson you learned from biology and how it perfectly explained something you were once hesitant about. Such as being insecure about your big ears – only to know from a biology trivia that ears never stop growing. You can then share how this help lessen your insecurity because you now know large ears are normal. 

Do you have a memory you won’t forget that happened during biology class? Narrate this story and explain why it’s something that left an impression on you. To give you an idea, you can talk about the first time you dissected an animal, where you first realized how complex organisms are and that they are made of many systems to function, no matter how small.

Gene action and heredity are evolving. If you have a genetic illness or know someone who has it, you can share your experience. Then explain what your genes have to do with the disease. Is it something you got from your parents? Did they inherit it from your grandparents? Finally, you can add what your parents’ and grandparents’ lives were like because of the disease.

Virology, another branch of biology, studies viruses and viral diseases. A recent example is the coronavirus pandemic, where more people realized the importance of knowing a virus’ origin, structure, and how they work. Write an essay where you explain how the pandemic operates, such as why people should wear masks, social distance, etc.

For this essay, you can write about how biology helps you care for your health. For example, you can include how biology helped doctors give you the appropriate diagnosis, how you had the opportunity to have the proper treatment, etc. 

If you want to write on a related topic, here are essay topics about nature you can consider for your next essay.

Mastering A Level Biology Essays: Smart Tips and Unbeatable Examples

[email protected]

Introduction

A Level Biology is a challenging but rewarding course that covers a wide range of topics, from DNA and genetic inheritance to ecosystems and biodiversity. The key to success in this subject lies in understanding and applying the core principles of Biology and expressing your understanding in well-structured, coherent essays. In this article, we will provide you with some essential tips for writing outstanding A Level Biology essays, as well as presenting clear examples to help you master the essay-writing process.

• Understand the essay question

The first and most important step in writing an A Level Biology essay is to clearly understand the question. Break down the question into its key terms and implications, and ensure you comprehend what the examiner is asking you to discuss. Make a note of any key words or phrases that should feature in your essay, as these will help you structure your response and ensure you cover all the necessary points.

• Plan your essay

Before you begin writing your essay, take the time to plan your response. Create an outline that maps out the main points you want to make, as well as the order in which you will discuss them. This will enable you to develop a logical and coherent argument that addresses all the key aspects of the question.

• Include an engaging introduction

An effective introduction is crucial to grabbing the reader’s attention and setting the tone for your essay. Begin with a general statement that links to the essay question, and then narrow down your focus to present your main argument or line of inquiry. Finish your introduction with a clear thesis statement, which outlines the central points you will cover in your essay, demonstrating a solid understanding of the topic.

Example: The discovery of DNA and the subsequent advancements in genetic research have proven instrumental in understanding the role of genetics ininheritance of traits and diseases. This essay will discuss the role of genetic inheritance in the development of several human diseases, namely: Cystic Fibrosis, Huntington’s disease, and Alzheimer’s disease, as well as the ethical implications surrounding genetic testing and treatment.

• Use specific examples to support your arguments

In A Level Biology essays, it is essential to provide examples that demonstrate your understanding of the material and support your claims. Try to include a range of examples from different areas of the subject to show that you have a comprehensive and in-depth understanding of the course material.

Example: Cystic Fibrosis is an example of a genetic disorder caused by a mutation in the CFTR gene, which results in thick and sticky mucus production in affected individuals. This condition can lead to respiratory and digestive complications, illustrating the significant impact of genetic inheritance on an individual’s health.

• Synthesize information from multiple sources

To demonstrate a high level of understanding, A Level Biology essays should integrate information from various sources, such as class notes, textbooks, and scientific articles. Be sure to support your ideas with specific references to the source material, and use your own words to explain the concepts in a clear and concise manner.

• Address counterarguments and controversies

In any scientific field, there are often debates and controversies surrounding key concepts and theories. To show a comprehensive grasp of the subject matter, be sure to address counterarguments and discuss opposing viewpoints in your essay.

Example: While genetic testing for diseases such as Huntington’s has the potential to provide valuable information for individuals at risk, there are ethical concerns about the potential misuse of genetic information by employers, insurance companies, and even government entities. Weighing the benefits of genetic testing and treatment against these ethical concerns is an ongoing debate within the scientific community.

• Write a strong conclusion

To wrap up your essay, restate your main argument and summarize the key points you have made. Provide a clear and concise conclusion that demonstrates the significance of your argument and its implications for the broader field of Biology.

Example: In conclusion, the role of genetic inheritance in human diseases, as illustrated by Cystic Fibrosis, Huntington’s disease, and Alzheimer’s disease, underscores the immense potential of genetic research to improve our understanding of human health. However, as we continue to advance our knowledge and develop new treatments and testing methods, it is crucial that we remain conscious of the ethical implications that come with such advancements in order to protect individuals’ rights and liberties.

• Proofread and edit your essay

Finally, make sure you thoroughly proofread and edit your essay to correct any grammar, spelling, or punctuation errors, and to ensure that your argument flows smoothly and logically. Consider asking a friend or peer to review your essay and provide feedback – a fresh perspective can help you identify areas for improvement that you may have overlooked.

In summary, mastering A Level Biology essays involves understanding the essay question, planning a clear and logical response, using specific examples and evidence, synthesizing information from multiple sources, addressing counterarguments and controversies, and crafting a compelling introduction and conclusion. By following these steps and using the examples provided, you will be well on your way to delivering high-quality, insightful essays that demonstrate an excellent understanding of the complex and fascinating world of Biology.

Good luck, and happy essay writing!

Biology is one of the most exciting areas of science, after all, without biology, we would not exist; our development as creatures is what makes everything else possible.

And it is also an incredibly diverse area of science. When many think of biology, they often think of the subjects they studied at school, things like cells or anatomy. However, biology includes some of the most dynamic fields of science, and there is still more to discover.

Essays about biology might focus on the more straightforward aspects of the subject, for example topics like cells and cell division, or comparative anatomy and the similarities between animals even from very different parts of the animal kingdom.

You might take a wider view of biology. And how living creatures adapt to their habitats and each other. This can be anything from looking at how humans manage to thrive whether they are in arctic wilderness, torrid deserts, or humid rainforests. Or even how animals themselves have adapted as humans have increasingly encroached on their habitats.

Or it could take a longer term, looking at how genetics and heredity work within organisms. And on an even longer term, how these contribute to evolution, and how those small adaptations eventually create new species.

The latest science also provides plenty of topics, biotechnology, and genetic engineering gives modern humans the potential to do things that might have taken millennia before. It means that we might be on the threshold of seeing previously devastating illnesses eradicated. But it might also mean rogue states can threaten us with a targeted virus or antibiotic resistant bacteria.

And, of course, you could explore the ethics of biology. Just because we can selectively alter our genes, should we? Do we risk creating inequality because of access to technology? And how do we handle emotive issues, like genetically altering animals to provide medicines or even organs for human use?

Because biology is the study of life, the range of essay topics is as diverse as life itself. But whatever topic you choose, it’s important to keep a scientific mind, and even on subjective issues, remember to back up your arguments with strong evidence.

When writing an essay on Biology, try looking through the samples on this page. They will help you see different people’s points of view and create your own masterpiece!

Infant Possibilities

Advancement in genetics and reproductive technologies have today allowed the doctors and parents to screen in vitro fertilized embryos for genetic diseases and select the healthiest of them all. The article, Infant Possibilities by Moyer, puts forth the possibilities of future babies with several glimpses of the works done by doctors and scientists to save the neonates from disorders possibly caused due to single gene mutations. Scientists have got the success in analysing genomes of the babies or new born ones so that specialists can search for all the potential genetic causes of diseases affecting neonates and that too in just 50 hours span. Scientists have recently made speedy advancements in their knowledge of the human genome and their capability to transfer and change genes. According to Moyer, this has given them an opportunity to cure genetically caused diseases in the future in the neonates and even in embryos by the procedure of replacing faulting sections of genome or DNA with healthy parts of the DNA. This procedure is known as germ line therapy and is conducted on eggs, sperms and even on a fertilized embryo. Moyer argues that if there is any change possible in the genetic makeup at the embryo phase then it is feared that scientists will be able to make use of genetic technologies for modifying embryos and choosing the desirable cosmetic characters in babies such as sex, blue eyes, brown hair and color of skin. But this is still not accepted by many parts of the world. As the process is extremely expensive, this privilege can only be availed by couples who can easily afford this technological advancement. This has given rise to a debatable situation that focuses on the future competition between the designer babies possessing advantageous traits and the naturally produced babies who will surely be inferior in their genetic makeup. In my opinion, I am bit wary on gene testing and editing on the genome of human embryos just for designing the babies but this technology advancement is for sure untill now the best as it presents the possibilities of curing or rather removing the genes of diseases in embryonic stage. However, this is for sure that genetically enhanced babies are inevitable in the future. I do not share Moyer`s vision for the future. I feel that the ‘future normal ones’ should not show their despair even if they are outmatched by the upcoming generation of designer humans. This is thanks to the science has opened the avenues of more advancements where a host of technologies right from chip implantations to gene therapy would permit the normal humans to transform and enhance themselves genetically. I think the future will be interesting as it is significantly guided by scientific advancements. If I am given a chance and I could afford to get a designer baby, I will surely go for this opportunity not because I would want a child for blue eyes or particular sex, rather I will prefer a designer child who is healthy genetic makeup-wise so that he or she has got this advantage of not acquiring any genetic disease in his/her life. So the only attribute I would be choosing would be health issues. Looking at the human genome product, scientists have successfully found out the genetic cause of Alzheimer Disease. Familial Alzheimer Disease-1 is caused genetically by the mutation in gene that encodes the amyloid precursor protein, i.e., APP;104760 on the chromosome number 21q (Mok 1513-e1). Actually, the disease is caused by only one of the any single gene mutation on the chromosome numbers 1, 14 and 21. Alzheimer Disease is one of the most common forms of dementia in case of elderly people. The disease is actually a neurodegenerative disorder that is characterized by neuropathologic outcomes of extracellular amyloid plaques and intracellular NFT or neurofibrillary tangles in those brain regions that are vulnerable (Mok 1513-e1). Alzheimer disease demonstrates genetically heterogeneous disorder where AD-1 is associated with chromosome 21q, AD-2 with chromosome 19; APOE*4 allele (107741), AD-3 is caused by mutation in the gene presenilin-1 on chromosome 14q and AD-4 is caused by mutation on 1q31 locus of PSEN2 gene (Mok 1513-e1). There are quite number of research works underway on the genetics of the Alzheimer Disease. There is an Alzheimer Disease Genetics Study Program conducted by National Institute of Aging supported by Research Medical Centre, Kansas City where large number of information (of about 1000 families where two or more members have been diagnosed with Alzheimer’s) is being gathered and analysed genetically for studying chromosome 21q (Cacabelos, Ramón, and Rocío Martínez‐Bouza 566-576). National Cell Repository for Alzheimer Disease is storing a great amount of DNA samples and clinical information for making them available for further analysis of genes in embryos so that such possibilities are created that any mutated gene is transformed with healthy gene (Cacabelos, Ramón, and Rocío Martínez‐Bouza 566-576). Research holds a great significance in genetic engineering as it has brought about new hopes in eliminating the chances of acquiring deadly diseases by the new kids on the block and even before they are born. However, the researchers have to face several challenges including resistance of religious institutions and NGOs.

Sat / act prep online guides and tips, the complete ib extended essay guide: examples, topics, and ideas.

International Baccalaureate (IB)

IB students around the globe fear writing the Extended Essay, but it doesn't have to be a source of stress! In this article, I'll get you excited about writing your Extended Essay and provide you with the resources you need to get an A on it.

If you're reading this article, I'm going to assume you're an IB student getting ready to write your Extended Essay. If you're looking at this as a potential future IB student, I recommend reading our introductory IB articles first, including our guide to what the IB program is and our full coverage of the IB curriculum .

IB Extended Essay: Why Should You Trust My Advice?

I myself am a recipient of an IB Diploma, and I happened to receive an A on my IB Extended Essay. Don't believe me? The proof is in the IBO pudding:

If you're confused by what this report means, EE is short for Extended Essay , and English A1 is the subject that my Extended Essay topic coordinated with. In layman's terms, my IB Diploma was graded in May 2010, I wrote my Extended Essay in the English A1 category, and I received an A grade on it.

What Is the Extended Essay in the IB Diploma Programme?

The IB Extended Essay, or EE , is a mini-thesis you write under the supervision of an IB advisor (an IB teacher at your school), which counts toward your IB Diploma (learn more about the major IB Diploma requirements in our guide) . I will explain exactly how the EE affects your Diploma later in this article.

For the Extended Essay, you will choose a research question as a topic, conduct the research independently, then write an essay on your findings . The essay itself is a long one—although there's a cap of 4,000 words, most successful essays get very close to this limit.

Keep in mind that the IB requires this essay to be a "formal piece of academic writing," meaning you'll have to do outside research and cite additional sources.

The IB Extended Essay must include the following:

• A title page
• Contents page
• Introduction
• Body of the essay
• References and bibliography

Additionally, your research topic must fall into one of the six approved DP categories , or IB subject groups, which are as follows:

• Group 1: Studies in Language and Literature
• Group 2: Language Acquisition
• Group 3: Individuals and Societies
• Group 4: Sciences
• Group 5: Mathematics
• Group 6: The Arts

Once you figure out your category and have identified a potential research topic, it's time to pick your advisor, who is normally an IB teacher at your school (though you can also find one online ). This person will help direct your research, and they'll conduct the reflection sessions you'll have to do as part of your Extended Essay.

As of 2018, the IB requires a "reflection process" as part of your EE supervision process. To fulfill this requirement, you have to meet at least three times with your supervisor in what the IB calls "reflection sessions." These meetings are not only mandatory but are also part of the formal assessment of the EE and your research methods.

According to the IB, the purpose of these meetings is to "provide an opportunity for students to reflect on their engagement with the research process." Basically, these meetings give your supervisor the opportunity to offer feedback, push you to think differently, and encourage you to evaluate your research process.

The final reflection session is called the viva voce, and it's a short 10- to 15-minute interview between you and your advisor. This happens at the very end of the EE process, and it's designed to help your advisor write their report, which factors into your EE grade.

Here are the topics covered in your viva voce :

• A check on plagiarism and malpractice
• Your reflection on your project's successes and difficulties
• Your reflection on what you've learned during the EE process

Your completed Extended Essay, along with your supervisor's report, will then be sent to the IB to be graded. We'll cover the assessment criteria in just a moment.

We'll help you learn how to have those "lightbulb" moments...even on test day!  

What Should You Write About in Your IB Extended Essay?

You can technically write about anything, so long as it falls within one of the approved categories listed above.

It's best to choose a topic that matches one of the IB courses , (such as Theatre, Film, Spanish, French, Math, Biology, etc.), which shouldn't be difficult because there are so many class subjects.

Here is a range of sample topics with the attached extended essay:

• Biology: The Effect of Age and Gender on the Photoreceptor Cells in the Human Retina
• Chemistry: How Does Reflux Time Affect the Yield and Purity of Ethyl Aminobenzoate (Benzocaine), and How Effective is Recrystallisation as a Purification Technique for This Compound?
• English: An Exploration of Jane Austen's Use of the Outdoors in Emma
• Geography: The Effect of Location on the Educational Attainment of Indigenous Secondary Students in Queensland, Australia
• Math: Alhazen's Billiard Problem
• Visual Arts: Can Luc Tuymans Be Classified as a Political Painter?

You can see from how varied the topics are that you have a lot of freedom when it comes to picking a topic . So how do you pick when the options are limitless?

How to Write a Stellar IB Extended Essay: 6 Essential Tips

Below are six key tips to keep in mind as you work on your Extended Essay for the IB DP. Follow these and you're sure to get an A!

#1: Write About Something You Enjoy

You can't expect to write a compelling essay if you're not a fan of the topic on which you're writing. For example, I just love British theatre and ended up writing my Extended Essay on a revolution in post-WWII British theatre. (Yes, I'm definitely a #TheatreNerd.)

I really encourage anyone who pursues an IB Diploma to take the Extended Essay seriously. I was fortunate enough to receive a full-tuition merit scholarship to USC's School of Dramatic Arts program. In my interview for the scholarship, I spoke passionately about my Extended Essay; thus, I genuinely think my Extended Essay helped me get my scholarship.

But how do you find a topic you're passionate about? Start by thinking about which classes you enjoy the most and why . Do you like math classes because you like to solve problems? Or do you enjoy English because you like to analyze literary texts?

Keep in mind that there's no right or wrong answer when it comes to choosing your Extended Essay topic. You're not more likely to get high marks because you're writing about science, just like you're not doomed to failure because you've chosen to tackle the social sciences. The quality of what you produce—not the field you choose to research within—will determine your grade.

Once you've figured out your category, you should brainstorm more specific topics by putting pen to paper . What was your favorite chapter you learned in that class? Was it astrophysics or mechanics? What did you like about that specific chapter? Is there something you want to learn more about? I recommend spending a few hours on this type of brainstorming.

One last note: if you're truly stumped on what to research, pick a topic that will help you in your future major or career . That way you can use your Extended Essay as a talking point in your college essays (and it will prepare you for your studies to come too!).

#2: Select a Topic That Is Neither Too Broad nor Too Narrow

There's a fine line between broad and narrow. You need to write about something specific, but not so specific that you can't write 4,000 words on it.

You can't write about WWII because that would be a book's worth of material. You also don't want to write about what type of soup prisoners of war received behind enemy lines, because you probably won’t be able to come up with 4,000 words of material about it. However, you could possibly write about how the conditions in German POW camps—and the rations provided—were directly affected by the Nazis' successes and failures on the front, including the use of captured factories and prison labor in Eastern Europe to increase production. WWII military history might be a little overdone, but you get my point.

If you're really stuck trying to pinpoint a not-too-broad-or-too-narrow topic, I suggest trying to brainstorm a topic that uses a comparison. Once you begin looking through the list of sample essays below, you'll notice that many use comparisons to formulate their main arguments.

I also used a comparison in my EE, contrasting Harold Pinter's Party Time with John Osborne's Look Back in Anger in order to show a transition in British theatre. Topics with comparisons of two to three plays, books, and so on tend to be the sweet spot. You can analyze each item and then compare them with one another after doing some in-depth analysis of each individually. The ways these items compare and contrast will end up forming the thesis of your essay!

When choosing a comparative topic, the key is that the comparison should be significant. I compared two plays to illustrate the transition in British theatre, but you could compare the ways different regional dialects affect people's job prospects or how different temperatures may or may not affect the mating patterns of lightning bugs. The point here is that comparisons not only help you limit your topic, but they also help you build your argument.

Comparisons are not the only way to get a grade-A EE, though. If after brainstorming, you pick a non-comparison-based topic and are still unsure whether your topic is too broad or narrow, spend about 30 minutes doing some basic research and see how much material is out there.

If there are more than 1,000 books, articles, or documentaries out there on that exact topic, it may be too broad. But if there are only two books that have any connection to your topic, it may be too narrow. If you're still unsure, ask your advisor—it's what they're there for! Speaking of advisors...

Don't get stuck with a narrow topic!

#3: Choose an Advisor Who Is Familiar With Your Topic

If you're not certain of who you would like to be your advisor, create a list of your top three choices. Next, write down the pros and cons of each possibility (I know this sounds tedious, but it really helps!).

For example, Mr. Green is my favorite teacher and we get along really well, but he teaches English. For my EE, I want to conduct an experiment that compares the efficiency of American electric cars with foreign electric cars.

I had Ms. White a year ago. She teaches physics and enjoyed having me in her class. Unlike Mr. Green, Ms. White could help me design my experiment.

Based on my topic and what I need from my advisor, Ms. White would be a better fit for me than would Mr. Green (even though I like him a lot).

The moral of my story is this: do not just ask your favorite teacher to be your advisor . They might be a hindrance to you if they teach another subject. For example, I would not recommend asking your biology teacher to guide you in writing an English literature-based EE.

There can, of course, be exceptions to this rule. If you have a teacher who's passionate and knowledgeable about your topic (as my English teacher was about my theatre topic), you could ask that instructor. Consider all your options before you do this. There was no theatre teacher at my high school, so I couldn't find a theatre-specific advisor, but I chose the next best thing.

Before you approach a teacher to serve as your advisor, check with your high school to see what requirements they have for this process. Some IB high schools require your IB Extended Essay advisor to sign an Agreement Form , for instance.

Make sure that you ask your IB coordinator whether there is any required paperwork to fill out. If your school needs a specific form signed, bring it with you when you ask your teacher to be your EE advisor.

#4: Pick an Advisor Who Will Push You to Be Your Best

Some teachers might just take on students because they have to and aren't very passionate about reading drafts, only giving you minimal feedback. Choose a teacher who will take the time to read several drafts of your essay and give you extensive notes. I would not have gotten my A without being pushed to make my Extended Essay draft better.

Ask a teacher that you have experience with through class or an extracurricular activity. Do not ask a teacher that you have absolutely no connection to. If a teacher already knows you, that means they already know your strengths and weaknesses, so they know what to look for, where you need to improve, and how to encourage your best work.

Also, don't forget that your supervisor's assessment is part of your overall EE score . If you're meeting with someone who pushes you to do better—and you actually take their advice—they'll have more impressive things to say about you than a supervisor who doesn't know you well and isn't heavily involved in your research process.

Be aware that the IB only allows advisors to make suggestions and give constructive criticism. Your teacher cannot actually help you write your EE. The IB recommends that the supervisor spends approximately two to three hours in total with the candidate discussing the EE.

#5: Make Sure Your Essay Has a Clear Structure and Flow

The IB likes structure. Your EE needs a clear introduction (which should be one to two double-spaced pages), research question/focus (i.e., what you're investigating), a body, and a conclusion (about one double-spaced page). An essay with unclear organization will be graded poorly.

The body of your EE should make up the bulk of the essay. It should be about eight to 18 pages long (again, depending on your topic). Your body can be split into multiple parts. For example, if you were doing a comparison, you might have one third of your body as Novel A Analysis, another third as Novel B Analysis, and the final third as your comparison of Novels A and B.

If you're conducting an experiment or analyzing data, such as in this EE , your EE body should have a clear structure that aligns with the scientific method ; you should state the research question, discuss your method, present the data, analyze the data, explain any uncertainties, and draw a conclusion and/or evaluate the success of the experiment.

#6: Start Writing Sooner Rather Than Later!

You will not be able to crank out a 4,000-word essay in just a week and get an A on it. You'll be reading many, many articles (and, depending on your topic, possibly books and plays as well!). As such, it's imperative that you start your research as soon as possible.

Each school has a slightly different deadline for the Extended Essay. Some schools want them as soon as November of your senior year; others will take them as late as February. Your school will tell you what your deadline is. If they haven't mentioned it by February of your junior year, ask your IB coordinator about it.

Some high schools will provide you with a timeline of when you need to come up with a topic, when you need to meet with your advisor, and when certain drafts are due. Not all schools do this. Ask your IB coordinator if you are unsure whether you are on a specific timeline.

Below is my recommended EE timeline. While it's earlier than most schools, it'll save you a ton of heartache (trust me, I remember how hard this process was!):

• January/February of Junior Year: Come up with your final research topic (or at least your top three options).
• February of Junior Year: Approach a teacher about being your EE advisor. If they decline, keep asking others until you find one. See my notes above on how to pick an EE advisor.
• April/May of Junior Year: Submit an outline of your EE and a bibliography of potential research sources (I recommend at least seven to 10) to your EE advisor. Meet with your EE advisor to discuss your outline.
• Summer Between Junior and Senior Year: Complete your first full draft over the summer between your junior and senior year. I know, I know—no one wants to work during the summer, but trust me—this will save you so much stress come fall when you are busy with college applications and other internal assessments for your IB classes. You will want to have this first full draft done because you will want to complete a couple of draft cycles as you likely won't be able to get everything you want to say into 4,000 articulate words on the first attempt. Try to get this first draft into the best possible shape so you don't have to work on too many revisions during the school year on top of your homework, college applications, and extracurriculars.
• August/September of Senior Year: Turn in your first draft of your EE to your advisor and receive feedback. Work on incorporating their feedback into your essay. If they have a lot of suggestions for improvement, ask if they will read one more draft before the final draft.
• September/October of Senior Year: Submit the second draft of your EE to your advisor (if necessary) and look at their feedback. Work on creating the best possible final draft.
• November-February of Senior Year: Schedule your viva voce. Submit two copies of your final draft to your school to be sent off to the IB. You likely will not get your grade until after you graduate.

Remember that in the middle of these milestones, you'll need to schedule two other reflection sessions with your advisor . (Your teachers will actually take notes on these sessions on a form like this one , which then gets submitted to the IB.)

I recommend doing them when you get feedback on your drafts, but these meetings will ultimately be up to your supervisor. Just don't forget to do them!

The early bird DOES get the worm!

How Is the IB Extended Essay Graded?

Extended Essays are graded by examiners appointed by the IB on a scale of 0 to 34 . You'll be graded on five criteria, each with its own set of points. You can learn more about how EE scoring works by reading the IB guide to extended essays .

• Criterion A: Focus and Method (6 points maximum)
• Criterion B: Knowledge and Understanding (6 points maximum)
• Criterion C: Critical Thinking (12 points maximum)
• Criterion D: Presentation (4 points maximum)
• Criterion E: Engagement (6 points maximum)

How well you do on each of these criteria will determine the final letter grade you get for your EE. You must earn at least a D to be eligible to receive your IB Diploma.

Although each criterion has a point value, the IB explicitly states that graders are not converting point totals into grades; instead, they're using qualitative grade descriptors to determine the final grade of your Extended Essay . Grade descriptors are on pages 102-103 of this document .

Here's a rough estimate of how these different point values translate to letter grades based on previous scoring methods for the EE. This is just an estimate —you should read and understand the grade descriptors so you know exactly what the scorers are looking for.

Here is the breakdown of EE scores (from the May 2021 bulletin):

How Does the Extended Essay Grade Affect Your IB Diploma?

The Extended Essay grade is combined with your TOK (Theory of Knowledge) grade to determine how many points you get toward your IB Diploma.

To learn about Theory of Knowledge or how many points you need to receive an IB Diploma, read our complete guide to the IB program and our guide to the IB Diploma requirements .

This diagram shows how the two scores are combined to determine how many points you receive for your IB diploma (3 being the most, 0 being the least). In order to get your IB Diploma, you have to earn 24 points across both categories (the TOK and EE). The highest score anyone can earn is 45 points.

Let's say you get an A on your EE and a B on TOK. You will get 3 points toward your Diploma. As of 2014, a student who scores an E on either the extended essay or TOK essay will not be eligible to receive an IB Diploma .

Prior to the class of 2010, a Diploma candidate could receive a failing grade in either the Extended Essay or Theory of Knowledge and still be awarded a Diploma, but this is no longer true.

Figuring out how you're assessed can be a little tricky. Luckily, the IB breaks everything down here in this document . (The assessment information begins on page 219.)
