Review books + college?

<p>Hi guys,
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?</p>

<p>I’m doing that right now. I kept the Barron’s Chem, Physics C and calc books. They’re basically like workbooks which is good because they can help you practice multiple choice which you will rarely see in a textbook. If you’re not going to use them though you might as well get your $20 a piece for them on ebay.</p>

<p>I kept the books for the subjects I knew I might look at again: AP Physics B (didn’t take the test, but our physics 1 course at my high school covered physics B, so I used it to be able to do better in the class), AP CS A (old from 2010 or so), AP Music Theory (but the new and old versions, my brother took the exam before they changed it), and AP Calc.</p>
