If you’re studying for AP Biology, YouTube can be your secret weapon. The right channels offer free, high-quality explanations of tough concepts, visual diagrams, and even complete unit-by-unit exam prep — all on demand.
But with hundreds of creators out there, how do you know which ones are worth your time?
In this guide, RevisionDojo has curated the best AP Biology YouTube channels based on:
- Accuracy and alignment with the College Board curriculum
- Depth of content (unit reviews, FRQ breakdowns, exam tips)
- Visual quality and pacing for learning
- Student feedback and proven results
1. Bozeman Science
Why It’s Great:
Paul Andersen’s channel is a classic in AP Bio prep. He explains each concept clearly, using diagrams and animations that make complex processes like the Calvin cycle and cell signaling easy to follow.
Best Videos to Start With:
- AP Biology Exam Review Playlist
- Cellular Respiration and Photosynthesis deep dives
- Lab Investigation walkthroughs
Pro Tip: Pair Bozeman Science videos with RevisionDojo’s unit guides for integrated review.
2. Amoeba Sisters
Why It’s Great:
Fun, cartoon-style animations that turn dry biology concepts into memorable stories. While a bit more casual, they’re fantastic for visual learners and for memorizing key vocabulary.
Best Videos to Start With:
- “Cell Transport”
- “DNA Replication”
- “Natural Selection”
Pro Tip: Use these videos for initial understanding, then move to more in-depth review content.
3. CrashCourse Biology
Why It’s Great:
Fast-paced, engaging, and narrated by Hank Green, CrashCourse delivers complete biology coverage in a condensed, visually appealing format. Great for big-picture understanding before diving into details.
Best Videos to Start With:
- The entire AP Bio playlist (40+ episodes)
- Ecology series for Unit 8 review
Pro Tip: Watch at 0.75x speed if the pacing feels too fast.
4. Maricopa Community Colleges – Biology Lectures
Why It’s Great:
This channel offers longer, lecture-style explanations that mimic a college biology class. Ideal for students who want deep dives into topics.
Best Videos to Start With:
- “Enzyme Function”
- “Cell Communication”
Pro Tip: Pause and take notes as if you’re in an actual lecture — you’ll retain more.
5. Khan Academy
Why It’s Great:
Khan’s AP Biology series is broken down into short, focused lessons on specific topics. They’re excellent for targeted review when you’re struggling with a single concept.
Best Videos to Start With:
- “Photosynthesis” series
- “Mendelian Genetics” series
Pro Tip: Combine Khan videos with their practice quizzes for active recall.
6. Science with Susanna
Why It’s Great:
A high school AP Biology teacher who specializes in FRQ strategies, data analysis, and exam-specific tips.
Best Videos to Start With:
- FRQ practice series
- “How to Read AP Bio Graphs”
Pro Tip: Use these videos during the last month before the exam to polish your test-taking skills.
7. RicochetScience
Why It’s Great:
Great animations and narrated diagrams for topics like protein synthesis, DNA replication, and cell signaling pathways.
Best Videos to Start With:
- “Signal Transduction Pathway”
- “Osmosis and Diffusion”
Pro Tip: Add timestamps to key processes so you can jump back quickly during review.
8. Melissa Maribel (Biology Focused Playlists)
Why It’s Great:
While she covers chemistry too, her biology playlists are clear, approachable, and great for reviewing fundamentals before tackling advanced topics.
Best Videos to Start With:
- “Biology Basics” series
- “Macromolecules”
Pro Tip: Ideal for students moving from general bio to AP-level rigor.
How to Use YouTube Effectively for AP Biology
Just watching videos isn’t enough. Here’s the RevisionDojo method:
- Step 1: Pick 1–2 videos per topic instead of binging
- Step 2: Take active notes using Cornell or outline style
- Step 3: Pause to sketch diagrams or write definitions in your own words
- Step 4: Follow up with practice questions immediately
FAQs – AP Biology YouTube Channels
Q: Can I just study from YouTube and skip textbooks?
A: No — YouTube is best as a supplement. Use it for clarification and reinforcement.
Q: How many hours a week should I watch?
A: Limit to 3–5 hours, focusing on your weakest topics.
Q: Which channel is best for FRQs?
A: Science with Susanna is especially strong for FRQ practice and scoring strategies.
Final Tips from RevisionDojo
- Match videos to the AP Biology units you’re currently reviewing
