<p>Someone just offered me Cliffs for 10$ and it's a really good deal, but I have to decide soon or they will sell to someone else. I want to get a 5, but I'm already really good at bio, how helpful would a review book be?</p>
<p>The CliffsNotes book is considered to be one of the best review books for AP Bio. I used it and I got a 4 on the test. The 4 was because I totally bombed the last FRQ, otherwise the MC was cake. The practice tests in the book are waaaay too hard. I missed 47 out of 100 on them. PR’s test, I only missed 17, but I would still go with too hard, rather than too easy</p>
