<p>I'm going to start preparing for the SAT subject exams in November and I wanted to know what your opinions on helpful preparation aids for the following exams:</p>
<p>Chemistry
Math II
US History</p>
<p>I've taken AP Chemistry and AP US History 11th grade so I'm relying on my notes and review book for that, but I also want a prep book that will refresh my memory on concepts and give practice questions that are like the ones on the subject exams.</p>
<p>As for Math II, I've taken all the math that's on it but I really need to prep as math is not my strongest subject. </p>
<p>What books/companies would you recommend for these exams? (aiming for 750+) </p>
<p>Thanks!</p>
