AP Biology

AP Sciences AP Biology

Learn about the core scientific principles, theories, and processes governing living organisms, biological systems, and natural phenomena.

Understand key science practices you can use to develop explanations and predictions of natural phenomena, which you will test and refine through laboratory investigations. Develop advanced reasoning and inquiry skills as you design experiments, collect and analyze data using mathematics and other methods, and interpret that data to draw conclusions.

About the Exam
The exam is approximately three hours long and has two parts — multiple choice and grid-in, and free response. Each section is worth 50% of the final exam grade.

Questions will assess your understanding of the big ideas, enduring understandings, and essential knowledge and your application of these through the science practices. These may include questions on the following:
  • the use of modeling to explain biological principles;
  • the use of mathematical processes to explain concepts;
  • the making of predictions and the justification of phenomena;
  • the implementation of experimental design; and
  • the manipulation and interpretation of data
Section I: Multiple Choice
1 hour and 30 minutes
  • Part A — 63 Multiple Choice Questions
  • Part B — 6 Grid-In Questions
The grid-in questions focus on the integration of science and mathematical skills. For these responses, you will need to calculate the correct answer for each question and enter it in a grid on that section of the answer sheet.

Total scores on the multiple-choice section are based on the number of questions answered correctly. Points are not deducted for incorrect answers and no points are awarded for unanswered questions.

Section II: Free Response
8 Questions (2 long and 6 short); 1 hour and 30 minutes, which includes a 10 minute reading period
