The Khan Academy's AP Biology page can be used to review individual topics throughout the course as you study for unit tests and quizzes and also to finish review the entire course for the AP Biology exam! 
 
They have a full course review that includes short videos (5-10 minutes) on each topic, topic quizzes (that score and analyze your results with correct answers and explanations), as well as unit tests that mimic the College Board AP Exam
