Frequently Asked Questions

Why Do I Need a Review Book?

You may not need a review book for all AP exams, but the AP Biology exam covers many complex concepts. There are hundreds of terms to know and apply correctly. You also have some free-response questions that require you to organize your thoughts and construct detailed, informative answers.

The AP Biology exam relies heavily on a student’s ability to apply concepts. Review guides help you see the bigger picture by breaking concepts down and providing detailed explanations. Many guides include additional online materials, and some provide tutorial videos to demonstrate lab concepts.

Living in a digital age, many classes rely on various materials instead of one textbook. If you don’t have a biology textbook for your class, a review guide is a great resource. It’s more convenient to have one book instead of several documents and links.

What Should I Look for in an AP Biology Review Book?

This question is complicated because it depends on the type of student. Assess your styles and needs before selecting a book because what works well for somebody else may not work for you. Try answering some of these questions about your approach to studying to narrow down your choices.

  • How do you learn best? Do you prefer videos or flashcards?
  • Did you struggle with any topics during the class? If so, you may want more detailed explanations or supplementary materials.
  • How much time do you have between now and the test?
  • Do you need help with planning and strategizing?
  • Is a variety of resources important to you? If so, you may want a physical textbook that includes online resources.
  • Do you need more practice tests or more practice questions?

How Should I Use a Review Book?

Start by asking yourself how comfortable you are with the material you learned over the year. Next, consider what type of learner you are and any weaknesses you might have in terms of the AP Biology exam.

If you did well in class and feel confident about your knowledge of each topic, you may want a book that focuses more on strategies and pacing. On the other hand, if you feel more confident in your test-taking abilities, you might prefer a book that explains the concepts clearly.

How Important are Practice Tests?

For most students, practice tests allow them to apply strategies, address pacing concerns, and discover gapsin content knowledge. They are also useful for establishing a baseline to determine areas you need to focus on before your test date.

Remember, AP exams are different from other standardized tests. Practice tests that include answers with detailed explanations help you understand the exam’s layout and what scorers want to see, especially regarding free-response questions.

Do I Really Need Online Resources and Flashcards?

Again, the use of online resources and flash cards is a personal decision. If you don’t like using virtual tools or flashcards for studying, they probably won’t help you much. However, those resources can enhance your experience and provide variety in your study tools.

How Much Time Do I Need to Spend Studying?

The amount of study time you require depends heavily on your mastery of the content and comfort with the testing style. Some students score high with limited review, while others need to devote more time.

It’s a good idea to start with a practice test to determine how much time you should devote to studying. Pretend the practice test is the real exam and follow the timing guidelines to find your baseline.

Check over your answers to see how you did. If you struggled to finish, you might need to devote time to strategies and pacing tips. Look for topics you struggled with and what types of questions challenged you the most. Create a list of gaps and build out your study time from there.

Is it Better to Study Alone or in a Group?

Only you can decide whether you should study alone or with a group of peers. Some students cannot handle the distractions or variations in study techniques. Others benefit from different perspectives and interactions with peers.

Studying alone prevents you from falling victim to distractions and needy peers. However, you have to hold yourself accountable for study time and reviewing the correct material.

If you decide to study with a group, make sure you trust your team’s competence. You don’t want to spend most of your study time bringing others up to speed on topics already mastered. Ideally, successful study groups work together to cover material quickly and efficiently.

You may find that a blend of solo and group study time gives you the best outcome. Feedback from peers creates discussion and the ability to practice the application of concepts. However, you won’t be testing with a group, so you need to be able to arrive at correct answers yourself.

Final Thoughts on AP Biology Review Guides

For most AP Biology students, the best review guide includes test-taking strategies, content review, and practice tests with answers and explanations. The structure and content covered on the AP Biology exam differ from other exams in complexity, so test preparation is slightly different.

Hopefully, this guide helped you to determine the best review book to prepare you for the AP Biology exam. Good luck on your exam!
