<p>From all the research i have done. The best book for self-studying AP Psychology is Barrons. There are two books on AP Psychology by Barrons. Which one should i buy or should i buy both if i want a 5?</p>
<p>I have the first one, and I got a 5 on the exam. Don't get it with the CD, because it's useless. I don't think anyone can really give you a review of the 2008 one, because it wasn't available last year.</p>
