<p>Cliffs AP has all you need in it. Just make sure to start studying a bit before the actual test (Read: Not 2 days before the test while studying for other AP’s) and you are basically guaranteed a 5.</p>
<p>I got a 4 on the test just studying from the book a few days before the test and didn’t really go over all the subjects in depth, if I had started earlier I know for a fact that I would have gotten a 5 with that book.</p>
