Prep Book Recommendations Please

<p>I haven't taken any of the SAT IIs yet and I want to self study over the summer heavily for these. What are the best prep books for each of the following subject tests:</p>

<p>Math IIc
US History
Bio</p>

<p>Side Note: I took Bio freshman year and am taking AP bio next year. Will I be able to do well on Bio with ample study + a good prep book?</p>

<p>USH - Kaplan's SAT II, but if you want a thorough review I suggest Amsco (AP)</p>

<p>Ya, I have the Amsco book for AP US. Didn't quite finish it before the AP though >_<. With all the spare time I have this summer I'll definitely give it a read. TY</p>
