AP Bio Prep Course

With 10 years of biology teaching experience, your coach Chloe knows what students want and need to breeze through the AP Biology exam with confidence! Biology can be easy and fun. Yes, even the hard stuff like biochemistry, labs and math.

Focused review

5 Saturday OR Sunday sessions lasting 5 hours each (total 25 hours)

Small Groups

Individual attention is important, so groups are kept small


Interactive games, mini-labs, demonstrations, animations and other fun tools to review a large amount of content in a short time

Diagnostic tests

Diagnostic tests, real AP practice questions, and free response questions graded using real AP rubrics


A thorough review of the AP lab objectives and science-skills practice

Free support

Ongoing, free support by email or phone between sessions

Full coverage

Covering the all-new exam (post 2012)

Since 2009, Chloe has helped many students achieve the scores they want in AP Biology. Many of them go on to top universities such as Princeton, UCLA, USC, Northwestern, NYU and Johns Hopkins.
