<p>Is Math II really necessary to take? I want to take the SAT chem plus another subject, would it be better if I take the math exam? or should I take physics or Biology? I am good at math though. and to get 800 should I study barrons or will only PR do?</p>
<p>you can take 3 subject tests in a sitting. Take math II, chem., and physics/biology.</p>
<p>Look up the colleges’ admission requirements.</p>
<p>I’d go with Barron’s. It’s far more detailed and overprepares you for the test. It’s always gotten me high scores. Princeton Review, I’ve noticed, frequently has errors and is inaccurate.</p>
