By the end of the article, you will also find tips on how to achieve a high score in the exam. This way, you can earn that much-needed college credit and get other benefits. Let the scrolling begin!
The Structure of The AP Biology Exam
If you want to enroll in the course and take up the AP biology exam, you must first get acquainted with its structure – it is three hours long. Also, the structure consists of main sections – the multiple-choice section and the free-response section. Further, for the year 2021, the exam took place in two modes – pencil and paper mode and digital mode. Let us discuss it further.
Paper vs. Digital AP Biology Exams
Due to the coronavirus pandemic, many AP exams in 2021 took place both in paper and digital mode. The same is the case with the AP Bio exam. Here is the difference between the two – the paper version of the AP Biology exam took place at school while the digital versions (on a computer) took place both at home and school.
Further, the school had the choice to decide which kind of version they wanted to administer. It means, they had the option to choose between the in-school paper mode, at-home digital mode, and in-school digital mode. While the mode of these exams is different, the college board tried to keep the exams as similar as possible.
All the AP Biology exams had the same difficulty level based on the content tested. However, since for the digital exam, students had to type using a keyboard, no drawings and graphs were asked on the paper. Also, the app used for the digital exam had all the symbols the students needed for their exams.
The Pattern of The AP Biology Exams – What’s on The Paper?
Above, we have answered one of your questions – “how long is the ap bio exam?” Now, here is what you have to answer in the exam. As already said, the exam consists of two sections – multiple-choice and free-response. Here are all the details about them that you must know:
AP Biology Multiple-Choice Section
Also called the grid-in quantitative section, this part of the exam has 60 multiple-choice questions that you have to answer in 90 minutes. All of these questions are designed to test your understanding of the fundamentals of biology and how you can apply these to solve problems. Here is what the questions are about:
- Visual representations
- Statistical tests and data analysis
- Concept explanations
- Questions and methods
- Representing and describing data
The other name of the section – grid-in quantitative section is because earlier (until 2020), it also comprised grid-in questions. These are the ones that have more than one answer correct. However, students do not have to worry about this. Now, the questions only have one answer correct out of the four given choices.
Key Points About the AP Biology Multiple-Choice Section
- It has 60 multiple-choice questions.
- Each question has four answer choices (A-D).
- The section is 90 minutes long.
- It is equal to 50% of the entire AP Biology exam score.
- It has both stand-alone questions and questions in sets.
- The sets may have 4-5 questions per set.
- The multiple-choice section is checked with the help of a computer.
AP Biology Free-Response Section
The second section, the free-response part, has long as well as short response questions. There are two long-response questions and four short-answer questions. While the former AP Bio FRQ focuses on analyzing experimental results, the latter covers the following topics:
- Scientific Investigation
- Analysis of Data
- Conceptual Analysis
- Analysis of Model
- Analysis of Visual Representation
Further, both the long-form questions require data analysis. The short ones, on the other hand, need only a paragraph-length response. Your response should explain and justify the given scenario. Moreover, where the multiple-choice section is scored using a computer, this one is graded by college and high-school teachers. They can give you partial credits for your answers if you are partially correct.
Key Points About the AP Biology Free-Response Section
- It has two long-response questions.
- Long-response questions carry 8-10 points each.
- It has four short-answer questions.
- Short-answer questions carry 4 points each.
- The second short-answer question needs you to graph something.
- The section is 90 minutes long.
- It is equal to 50% of the entire AP Biology exam score.
- The free-response section is graded by college and high-school teachers.
AP Biology Exam Expectations
Below, you can find what both the AP Biology exam sections expect you to know. Have a look:
- You must know how to interpret data.
- You need to understand how to use graphical and mathematical models to explain basic principles and concepts related to Biology.
- You must know how to implement your knowledge of all the concepts.
- You need to make predictions and also know how to justify events based on biological principles.

Scoring of The AP Biology Exam
For the AP Biology exam, the multiple-choice section and the free-response section make up 50% of your score each. For the former, you get 1 point for each question you answer correctly. Also, there is no negative marking for incorrect or blank answers. So, you can easily calculate your raw score.
For the free-response section, scoring is a bit more complicated. The section is scored by actual graders rather than a computer. Further, you don’t need to get full marks. The section has partial scoring.
When you get the scores for both sections, you will need to do a couple of calculations to get the final score (1-5). Any AP Bio score calculator online can help you with it. Manually, you can do the following:
- Firstly, multiply your multiple-choice section points by 1.03.
- Then, multiply the two long free-response question points by 1.5.
- After this, multiply the short free-response question points by 1.43.
- Lastly, add them all to get your raw AP Biology exam score.
If your raw score is between 92-120, your AP score will be 5. Similarly, here are what other scores correspond to:
- 72-91 Raw Score: AP Score 4
- 52-71 Raw Score: AP Score 3
- 31-51 Raw Score: AP Score 2
- 0-30 Raw Score: AP Score 1
What to Bring to the AP Biology Exam?
For the digital AP Biology exam, a laptop/computer is needed. If you are taking it at a testing location, make sure to arrive early. On the other hand, those taking it from home must confirm their digital login details beforehand. Then, for the paper mode, bring the following:
- 2 sharpened No. 2 pencils (for multiple-choice section)
- 2 pens with black or blue ink (for free-response questions)
- Four-function, scientific, or graphing calculator

AP Biology Exam At-Home Study Tips
While it is advised to take up AP Biology classes, you can also study yourself for the exam. Also, even if you take up the classes, self-preparation is crucial. Here are some tips for it:
Always Be Consistent
First things first, always take out time for studying and preparing daily for the AP Biology exam. Even if your study time is a few minutes to an hour a day for the subject, be consistent with it. When you study every day, you are sure to get done with the concepts by the time your APs arrive in May.
Focus On Key Terms
Then, focus on all the crucial terms. Use flashcards and study guides to memorize them. You can either make flashcards the old-fashioned way for it or use various study apps available online. This way, you can study even on the go.
Get Rid of Distractions
Then, make sure to get rid of everything that distracts you. After all, these days, it can be really easy to become distracted during studying. During your study time, stay away from all these things.
Study with A Friend
It is also a good idea to study with a friend occasionally. You might talk out concepts and guide each other. Also, this way, you will study at a regular pace and not slack off. The only thing you need to take care of here is that your planned study time should focus on studying.
Use Your Calculator
Lastly, when you study at home, do not use your phone as a calculator. Instead, use a real calculator that meets the requirements for the exam.
AP Biology Exam Tips for Multiple-Choice Questions
Our next set of tips is solely focused on the multiple-choice section of the AP Biology exam. Have a look at them:
Manage Your Time
For the 60 multiple-choice questions, you will have only 90 minutes. Therefore, divide your time well. During your first pass through the questions, never spend more than 2 minutes on a question. If you are stuck on a question, move on to the next one and come back later. Also, since there is no negative marking, fill in an answer for each question.
Imagine the Question
When you read a question in your AP Biology exam, form a mental image of the question. Then, look at the answer choices and see if any of them matches the image you have in mind. Justify why you eliminated the others and once you are sure about your answer, mark it. If you cannot choose an answer, make your best choice since no mark is deducted for a wrong answer.
Examine Visual Materials Carefully
When it comes to visual materials, you must know how to interpret them correctly to know the answers. For it, carefully examine any labels, titles, axes, etc. Also, go through tables, figures, graphs, or images with utmost precision.
Handle Questions Grouped Like Sets Wisely
There are a few sets of 2-4 questions in this section. All of these questions are related and typically associated with one or more images, figures, tables, etc. While they are related, do not give up if you cannot crack the first question. Most of the time, each of the questions in the set can be answered independently too.
Re-check Your Answers
Always make sure that you have at least 10-15 minutes at the end of the exam to check your answers. Manage your time accordingly. During these 10-15 minutes, guess the answers to the questions you have not answered. Do not leave any questions unanswered. Also, start from the first page, and check if all your answers are correct.
AP Biology Exam Tips for Free-Response Questions
After the exam tips for multiple-choice AP Biology questions, here are some of our best tips for AP Bio free-response questions. Go through them!
Follow These 5 Must-Do’s
- Do not restate the question when answering a free-response question. It is not needed at all and wastes time. In place of it, simply answer what the question is asking directly. In simple words, your response should not beat around the bush and be to the point. However, do not provide only a single sentence answer to a question.
- If the free-response question is broken into parts, pay attention to each of them. Answer all parts while taking care of answering only what each question is asking. In the case of questions that require calculation, always mark your final answer. The work of how you reached that answer is also important.
- When making a table or graph for the long-answer question, follow standard conventions. It means that your graph or table must have a title with labeled columns, units, plot lines, etc. Here again, draw the line/curve only through the provided data. Never extrapolate anything if not asked.
- For all the free-response questions, points are rewarded for quality over quantity. Writing a lengthy answer will not get you points if you do not answer what the question asks clearly.
- Lastly, for all the questions that involve making an argument, follow the “claim-evidence-reasoning” structure.
Alongside all these five rules, you must do the following:
- Always keep track of time as you get only 90 minutes to complete the section. Make sure that you have time for revising your answers at the end.
- Also, understand the scoring rubrics provided by the College Board. Make sure to check all the related guidelines before you appear for the AP Biology exams.
- When writing the answers, focus on Grammar and spelling. It is also a great idea to underline or circle keywords in your answers.
- Outlines, diagrams, or bulleted lists alone are not acceptable in the section. Therefore, make sure to write complete sentences and paragraphs if you want your answers to be scored.
Final Thoughts: AP Biology Test Day Tips
So, this is all you need to know about the AP Biology exam. While the exam is challenging, consistent practice can easily help you get through it. Also, on the test day, take care of the following:
