<p>Im taking these in May and was wondering which company produces the best prep book for each of these tests. I have my brother's old Math2C book by Princeton review.</p>
<p>Barrons is awesome for Bio
Kaplan is good for Math IIC.. try looking at precalc books too.. it helps
Use either Princeton review or REA AP for SAT II US</p>
<p>Barrons is good for Bio. </p>
<p>If you want to overstudy, buy the cliffsAP notes for the AP Bio test. You'll gaurentee yourself a 750+.</p>
<p>For Math iic, Princeton Review is good, and if you want to overstudy, use Barrons.</p>
<p>bump, thx guys. anymore suggestions?</p>
<p>US History is Barron for sure. I got a 800 just reading through dat.
Bio...barrons again.
Math IIC is kaplan.</p>
