AP Biology exam: know the test content, format, and pacing

Students planning ahead for AP success need to know not only what's tested on the exams but also how the tests are structured.

Here's an overview of the AP Biology exam, including what students can expect from this year's digital tests.

What's on the AP Biology test?

The AP Biology exam is designed to measure your mastery of the fundamental concepts and scientific principles that govern biological systems and living organisms. Furthermore, the exam tests your ability to utilize the scientific method and analyze data.

The course involves 8 major units of study:

  1. Chemistry of Life
  2. Cell Structure and Function
  3. Cellular Energetics
  4. Cell Communication and Cell Cycle
  5. Heredity
  6. Gene Expression and Regulation
  7. Natural Selection
  8. Ecology

How is the AP Biology test structured?

The AP Biology exam is a two-part test consisting of a multiple-choice section followed by a free-response section. A graphing, scientific, or four-function calculator is permitted on all parts of the exam.

Because the AP Biology exam is a timed test, you will have to carefully pace yourself. This includes making determinations about whether you should skip and guess on any questions. In order to achieve the best possible score, you need to answer as many questions correctly as possible.

As you prepare for test day, you may come up with a personalized pacing plan, but as a starting point, here are rough guidelines based on the timing of each section:

  • Multiple choice:
    • 90 minutes to answer 60 questions
    • 1.5 minutes per question
  • Free response:
    • 90 minutes to answer 6 questions
      • 2 long-response questions: aim for 22 minutes per question
      • 4 short-response questions: aim for 11.5 minutes per question

 

What will this year's digital exams look like?

The College Board will offer multiple exam dates and formats to AP students in 2021. There will be three testing dates for each subject. On certain dates, schools can offer digital exams that may be administered either in school or at home. The AP Biology exam will be offered on May 14 (paper exam in school), May 27 (digital exam in school or at home), and June 11 (digital exam in school or at home).

While the digital exam will follow the same structure as the paper exam, students will want to take note of a couple subtle differences resulting from the digital testing interface:
