Go over old quiz hints and old quizzes.

Make sure you know the multiple choice questions (and their respective answers) in the AP Biology Cliffs Note Book. I promised that those who purchased this book would be handsomely rewarded for their efforts. I am keeping my promise.

Also, make sure you know all the details about the Five Conditions of Hardy-Weinberg and violations of them. The meaning of things like “Genetic Drift” , “Bottleneck Effect”, “Founder Effect”, “Gene Flow”, etc.

This is not a comprehensive list. These are just a few nuggets that you will probably see on the test.
