In addition to your text book and teacher’s notes, it would be useful to get a couple of study guides and practice test books.
Here is a list of some books that I would pick. The cheapest way would be to buy them from Amazon or The Book Depository. If you purchase your books using my links, I get a small commission that would help me sustain this website!
Reviews coming soon!
1. Biology 8th edition, by Campbell & Reece – THE textbook for AP and IB Biology
