AP Biology Exam Format: Timing, Structure, and More

Updated: Oct 24, 2023

The Advanced Placement (AP) Biology exam is a rigorous assessment that challenges students' understanding of biology concepts and their ability to apply them. To succeed on this exam, it's essential to have a clear understanding of its format, including the timing of each section and what to expect on test day. In this post, we will lay out exactly what the AP Biology exam format is, covering the duration of each section, the timing, and the schedule of the exam each year.

How Long is the FRQ Section?

The Free Response Questions (FRQ) section of the AP Biology exam is a critical component that assesses your ability to apply biological knowledge and demonstrate your problem-solving skills. Since 2020, the FRQ section consists of two long free-response questions and six short free-response questions.

In terms of timing, the FRQ section of the AP Biology exam spans a total of 90 minutes. This means you have approximately 90 minutes to complete all eight questions. It is important to manage your time effectively to ensure that you allocate an appropriate amount of time to each question. For example, you should aim to spend around 22 minutes on each long free-response question and approximately 9 minutes on each short free-response question.

Thee 2 long free-response questions which are always at the beginning of the FRQ section. They often require more in-depth responses including multiple parts, data analysis, and essay-style answers. In contrast, the short free-response questions are usually more focused and require concise answers.

How Long is the MCQ Section?

The Multiple Choice Questions (MCQ) section of the AP Biology exam is designed to assess your knowledge of key biological concepts and your ability to analyze data. This section consists of 69 multiple-choice questions.

The MCQ section of the AP Biology exam also has a duration of 90 minutes. Just like the FRQ section, effective time management is crucial here. You have approximately 1 minute and 18 seconds per question, which may seem like a relatively short time. However, some questions may be quicker to answer, allowing you to allocate more time to more challenging ones.

The MCQ questions often cover a wide range of topics within biology, including genetics, ecology, cellular processes, and evolution. Be prepared to demonstrate your knowledge across these areas.

Tips for MCQ

One common question we get from students is: should I skip an MCQ I don't know or should I guess? The answer is, take a guess. Students are not penalized for incorrect answers or guessing on the AP exams. The other tip is to save difficult or lengthy MCQs for later. Mark them down and save 5-10 minutes at the end to review the skipped problems.

Timing on the AP Biology Exam

Understanding the timing of the AP Biology exam is vital to your success. The entire exam, including both the MCQ and FRQ sections, takes approximately 3 hours and 15 minutes to complete. However, it's important to keep in mind that there is an additional 10-minute break scheduled between the MCQ and FRQ sections.

Here's a breakdown of the timing for the AP Biology exam:

MCQ Section: 90 minutes (followed by a 10-minute break)

FRQ Section: 90 minutes

With the break included, the total duration of the exam is approximately 3 hours and 15 minutes. It's a very long exam, so we recommend using the break to refresh your mind and take a short rest. This can help you stay focused during the FRQ section!

When is the Exam Each Year?

The AP Biology exam is administered by the College Board, and its schedule remains fairly consistent from year to year. Typically, the exam is offered in early to mid-May, and the specific date varies slightly from year to year.

It's important to check the official College Board website or contact your school's AP coordinator for the most up-to-date information regarding the exam date for a given year. This ensures that you have accurate information and can plan your preparation accordingly.

In addition to the standard in-person exam, the College Board also offers online AP exams in certain circumstances. These online exams have their own schedules and requirements, so it's essential to stay informed about any updates or changes if you plan to take the exam online.


The AP Biology exam format is structured with a balance of multiple-choice and free-response questions and each section is 90 minutes long. Understanding the timing of each section, allocating your time effectively, and staying informed about the exam date are key elements of successful preparation.

By familiarizing yourself with the format and following a well-structured study plan, you can maximize your chances of earning a high score on the AP Biology exam. Remember that diligent preparation, practice, and effective time management are key to your success on test day. Good luck!
