The biology archive contains legacy biology content, and is not being updated with new content. Exercises and mastery mechanics will soon be removed from the biology archive. For our most up-to-date, mastery-enabled courses, check out High School Biology and AP Biology!
In this course you’ll explore the amazing world of biology through topics like biochemistry, cell biology, genetics, evolution, and ecology. To make sure you’re prepared with the fundamentals, we recommend completing high school biology before diving into AP Biology.
