<p>I already have Barron's for AP Psych and so far I've been doing pretty good with it for my summer assignment. But I need help choosing for these classes:</p>
<p>AP Chemistry
AP World History</p>
<p>For Chem, nearly all the 2014 "revised" editions review books have crap ratings. The only one being really good is crash course at 4 and half stars on Amazon. Can anyone confirm if Crash Course is the way to go? </p>
<p>And for WH, I heard that Princeton Review was better than all the other books including Barron's which was more in depth than PR. </p>
<p>Thanks </p>
