Best Sat Ii Books????

<p>i have a long time to study for the sat IIs (chem and us hist in may and math IIC in june) and am currently taking AP US History, AP Chemistry, and Honors Precalculus. What are the best books for the following subject tests if one can devote a large amount of time to them and is looking for a 750+?</p>

<p>united states history?
chemistry?
math level IIC?</p>

<p>get barron's for math 2. it's very thorough and even extraneous at some points. it will get you an 800 though...</p>

<p>bump for us hist and chem</p>

<p>Princeton Review for CHem and US History</p>
