about the AP Biology cheatsheets
A cheatsheet condenses a whole course into the facts you actually need on exam day. The AP Biology cheatsheets on this page summarize the key formulas, concepts, and definitions from each unit so you can review the entire course at a glance.
They work best as a final review: skim the one-page summary, spot the units you want to strengthen, then go deeper with the AP Biology study guides. The visual cheatsheets in the gallery are organized by unit, and you can generate your own for any topic you want a quick refresher on.
