<p>I personally used REA for AP European and got a 4, but a lot of my friends used Princeton Review and got a mix of 3s and 4s.</p>
<p>What about for Ap US?</p>
<p>for APUSH, REA (for the facts) and Princeton Review (for practice tests)</p>
<p>Good books for AP chem-
Princeton Review gives you what you need to know for the test (I got a 5 :)
APCliffs Chemsitry is good for labs</p>
<p>For AP US history, use Amsco the month (or week) before the test. I got a 5. Although Princeton Review works too...a friend got a 4</p>
<p>rea is huge for us history great for tests, excellent for review, and even gives several of the tests online with timer</p>
<p>for Psychology, theres a review book called "5 Steps to a 5" AP Psychology; I'm using this as a supplement to my textbook and I'm finding their interpretations and practice questions very helpful.</p>
<p>like "10 Reals", but for AP calculus:

<p>I know you said you bought the PR AP Economics - which I also used, as it's very good for review. However, if you feel that you need to <em>learn</em> on your own (as I self-studied micro), Barron's is very good.</p>
