What is the AP Biology Exam?

The AP Biology Exam is a college-level assessment administered by the College Board that measures students' understanding of introductory biology concepts typically covered in a two-semester college course. A qualifying score can earn college credit or advanced placement at participating universities across the United States.

What is the format of the AP Biology Exam?

The exam is 3 hours long and divided into two sections. Section I contains 60 multiple-choice questions (90 minutes, 50% of score), and Section II contains 6 free-response questions including 2 long and 4 short answers (90 minutes, 50% of score).

How many questions are on the AP Biology Exam?

The exam contains 66 total questions: 60 multiple-choice questions in Section I and 6 free-response questions in Section II. The free-response section includes 2 long-form questions (interpreting and evaluating experimental results, modeling biological phenomena) and 4 short-answer questions.

What score do I need to pass the AP Biology Exam?

AP exams are scored on a 1-5 scale, with 3 considered passing. A score of 3 is 'qualified,' 4 is 'well qualified,' and 5 is 'extremely well qualified.' Most colleges grant credit for scores of 4 or 5, though some accept 3 for general elective credit.

What topics are covered on the AP Biology Exam?

The exam covers eight units: Chemistry of Life, Cell Structure and Function, Cellular Energetics, Cell Communication and Cell Cycle, Heredity, Gene Expression and Regulation, Natural Selection, and Ecology. Questions also test four Big Ideas: evolution, energetics, information storage, and systems interactions.

Who is eligible to take the AP Biology Exam?

There are no formal prerequisites to take the AP Biology Exam. Any student, whether enrolled in an AP Biology course or self-studying, can register through their school or a participating school. Homeschooled students and those whose schools don't offer AP Biology can contact AP Services to locate a testing site.

How do I register for the AP Biology Exam?

Registration is handled through your high school's AP coordinator, typically by the fall deadline (usually November 15). The 2026 exam fee is approximately $98 in the United States, with fee reductions available for eligible low-income students. Late registration may incur additional fees.

What are the best ways to prepare for the AP Biology Exam?

Effective preparation includes reviewing the Course and Exam Description from the College Board, practicing free-response questions from past exams, mastering lab investigations and data analysis, and taking full-length timed practice tests. Focus on understanding scientific processes and experimental design rather than memorizing facts.

AP Biology Exam 2026

The AP Biology Exam 2026 is a comprehensive test that covers the study of living organisms. Students taking the course will explore topics such as biological diversity, evolution, and cellular physiology.

The exam is a challenging college-level course that can prepare students for advanced college courses and earn them credits. Many schools offer credit for a top score on the exam, and some require a student to complete a prerequisite biology course before receiving AP credit.

As with any AP exam, study practice is crucial to getting a good score on the test. Free response questions from past exams (from 1999 to present) are a great place to start. But, keep in mind that the AP Biology exam has changed drastically since 2013, so avoid using questions from exams before then.
