<p>Princeton review for Chem and REA for US History.</p>
<p>I second the Chemistry Princeton Review book. I have it and it's easy to understand and has lots of practice problems.</p>
<p>if you want something with a little more detail, but is great too, its arco... or now "Peterson's AP Chemistry," NOT AP Success.</p>
<p>I'm using Barron's for AP Chem. I like the detail it has, but a lot of people I know use Cliff's Notes or PR. Also for APUS I use REA and AMSCO. AMSCO has a pretty good summary and realistic multiple choice questions. REA is really brief in the explanation part but has like so many practice tests. I would say buy them both.</p>
<p>don't use barrons for chemistry...it is a TOTAL waste of your time</p>
<p>I studdied PR CHEM in the last two days before the exam and recieved a 5.</p>
<p>May I ask why it's totally waste of time to study Barron's books?</p>
<p>Barrons, for AP Chemistry, contains useless information such as the chemicals in sald dressing and stuff. Plus, plenty of errors and absolutely no strategies. It's like another textbook. For REVIEW and good practice questions choose PRINCETON REVIEW.</p>
<p>AMSCO is really good for AP USH</p>
