The AP Biology Practice Exam is one of the most important tools in your preparation arsenal. While quizzes and short drills help you learn individual concepts, a full-length practice exam replicates the real test experience — from timing to mental stamina.
This guide will walk you through where to find official and unofficial practice exams, how to take them effectively, and how to use your results to create a targeted study plan.
