<p>I’m hoping to take the following tests:</p>
<p>Spanish
Math II
US History
World History
Biology (maybe)</p>
<p>Which are the best books to use? I’ve heard that PR is pretty good, and that Barron’s overpreps you which is good, but has lots of mistakes which aren’t so good, and that Kaplan’s is too easy. And, I have a copy of Cliff’s AP Biology on my computer that someone recommended for the bio test. Is that sufficient to review for the test? (It seems to have more material than my college-level course bio textbook :P) I will definitely be getting the Official Blue Books from CB for US/W History and Math, if for nothing but for the previously used practice tests. (Am I correct?)</p>
<p>Any advice would be greatly appreciated =)</p>
