Free AP Biology Resources
Before diving in, let’s review the essentials. The AP Biology exam covers a wide range of biological concepts, such as molecules, cells, ecosystems, and evolution. Unlike other science courses, AP Biology places a strong emphasis on data analysis, scientific reasoning, and applying concepts rather than rote memorization.
If you're short on time and need a quick cram session, here are a few helpful resources:
AP Biology Study Kit: A one-stop shop for mastering exam content. Includes practice questions, practice tests, flashcards, games, and more!
College Board: Offers information you'll need to know leading up to, during, and after exam day.
What You’ll Learn in AP Biology
This course focuses on four Big Ideas that connect biology’s core principles:
Evolution – The process that drives the diversity and unity of life.
Cellular Processes – Structure, function, energy transfer, and communication within and between cells.
Genetics and Information Transfer – DNA, gene expression, and inheritance.
Interactions – How biological systems interact and influence ecosystems.

Exam Tips and Study Strategies
Upload your notes: Upload your notes to Thea. We have the AP Biology Study Kit built in for free use, but your teacher may touch on topics not always covered.
Practice Free-Response Questions (FRQs): The FRQs require you to analyze data and apply biological concepts. Use Thea’s Smart Study feature to practice!
Watch Videos: AP Biology is concept-heavy—visual explanations can help! Find some YouTube videos on tricky topics and upload the link to Thea to quiz yourself on what you learned.
Use Diagrams and Charts: Biology is highly visual. Use labeled diagrams, flowcharts, and concept maps to reinforce connections between ideas.
Review Frequently: Don't cram the week before! Spend 15-30 minutes a day on Thea leading up to the exam to ensure you're fully prepared.
How Hard Is the AP Biology Exam?
AP Biology is known for being one of the more challenging AP exams because it requires both memorization and the ability to apply knowledge in novel situations. However, with smart studying and consistent practice, it's completely manageable!
Final Thoughts
With determination and effective study habits, you can master AP Biology and crush the exam. Use the resources, study consistently, and practice applying your knowledge. You've got this—good luck on your journey to a 5!
