<p>I'm currently taking AP biology, and i'd like to self study for something like psychology, and chemistry ap tests. Is there some certain material you guys use or do you guys use PR, Kaplan, and Sparknotes etc.</p>
<p>Chemistry: Princeton Review
Psychology: Barrons</p>
<p>Definitely Barrons for psychology. It's very easy to self-study.</p>
<p>Some colleges require you to have lab experience for Ap chem. You might want to check out the colleges you are applying to.</p>
