The revised AP Biology course is focused on enduring, conceptual understandings and content that supports these understandings. The emphasis of the course is on learning essential concepts and reasoning skills. It is the equivalent of a two-semester college introductory class. Our free AP Biology practice test is a great place to start your exam prep.

AP Biology Exam
The AP Biology test is divided into two sections. Section I is multiple choice and Section II is free response. You have 90 minutes to complete each section, and each section will account for half of your grade.
Part A of Section I consists of 63 multiple choice questions. Part B of Section I consists of 6 grid-in questions, in which you will need to integrate your math and science skills in calculating the correct answers. After solving the problem you will write in (or “grid-in”) the exact answer that you have calculated.
Section II begins with a 10 minute reading period. You will then have 80 minutes to answer 2 long free response questions and 6 short free response questions. Students are allowed to use simple four-function calculators on the entire exam.
