AP Biology Prep Book by Pearson EducationThis review book is the perfect match for Cambell’s Biology in Focus and works perfectly to prepare you for the AP Biology Exam.

Pearson Education’s Text Prep Series for AP Biology  has a strong core focus on simply preparing you for the types of questions that you’ll get on the real exam, and contains many real life questions from previous years. All the other prep books try to blend teaching concepts and teaching how to write the test, where this one is focused primarily on the test and makes the assumption that the student already has the Cambell Biology in Focus textbook.

The “must-know” section is also great as it lets you do a quick rundown before the test to make sure you know all of the most important topics before the exam.

Self-Study Tips

Self studying for the AP Biology exam is fairly simple if you’re willing to put in the work.

All you need to do is go through the two books found above, take all of the practice tests, and you will be 90% of the way there.

You are also required to understand lab data for the test and the best option for self-studying labs is buying this lab manual from Pearson and doing the labs online with the aid of the manual. It’s not the same as the real thing, but it’s more than enough to prepare you for the long lab-related free response question on the exam.

Other Study Materials

  • CollegeBoard– The sample multiple choice and free response sections start on page 129 of the AP Biology Course & Exam Description PDF and they also have some questions from older tests.
  • VarsityTutors– They have 10 diagnostic tests and 369 practice tests which should be more than enough.
  •– They have 1155 practice questions, but you can only answer about 30 if you’re on the free plan. Still worth checking out though!
  • AP books– Even if you plan on only using online resources to study get at least one physical book. Trust us on this. You’ll need it.
