Hi there! You may have noticed things have changed on this site. You can learn more about that here
I was wondering if anyone knows if AP review books are helpful to keep? Like for biology: I have Baron's review book, and I was wondering if keeping it for when I have to take Biology 101 in college (as I decided not to take the exam after all) would be helpful. Same goes for my books for stats, environmental science and psych. Thoughts?
