About the Exam


The AP Biology course is the equivalent of an introductory two-semester college biology course. It is designed for students who have already completed one year of high school biology and one year of chemistry. The four “Big Ideas” covered in the course are:

1.) The process of evolution drives the diversity and unity of life.

2.) Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis.

3.) Living systems store, retrieve, transmit and respond to information essential to life processes.

4.) Biological systems interact, and these systems and their interactions possess complex properties.

The focus of the course is on understanding concepts rather than memorizing technical details and terminology. Laboratory work is a required element of all AP Bio courses, with an emphasis on the scientific method, problem solving, and research techniques.

The AP Biology Exam format is:
Multiple-Choice (90 minutes, 50% of final grade)
-63 multiple choice questions and 6 grid-in questions
Free-Response (90 minutes including a 10 minute reading period, 50% of final grade)
-2 long free-response essay questions and 6 short free-response questions

When is the AP Biology Exam?

The AP Biology Exam date for the 2014/2015 school year is Monday, May 11th 2015 at 8 a.m. The test is only offered once per year.
