<p>So i have cliffsnotes for my ap bio exam coming up in may. i know the tests are differently, obviously. but is it still safe to study from it for the satIIs? can anyone recommend another one? I'm also planning on taking the world history and us history as well. recs, please?</p>
<p>I am planning on taking AP US History and AP Chem in May. I am using AMSCO for US. and Princeton Review for AP Chem. Would you think they will be relevant enough to cover the material in the SAT 2 US and SAT 2 Chem?</p>
<p>For preparation, AP books are probably fine. However, it's extremely important to do at least a few practice tests in order to familiarize yourself with the format and other details of SAT Subject Tests, so try and acquire some tests that you can do.</p>
