AP Biology Mid-Year Prep

Starts

I'm Colton, and every Saturday, we will go over one unit covered by the AP Biology course curriculum guided by College Board. I scored a 5 on the 2025 exam and hope to make lessons that are fun, engaging, and educational. I plan on going deeply in-depth starting with unit 1 all the way to unit 8. This course is perfect if you are taking AP Biology this year and want extra practice or help! I will add more sessions as the course progresses.

The primary textbook we are using will be Campbell Biology. This series is created for students with no prior knowledge of biology but who are planning to take either Honor or AP Biology in the near future.
