Looking for book for AP Psychology

<p>All right. </p>

<p>I'm looking for a good study book for AP Psychology. </p>

<p>I was looking at either Princeton Review or Barron.</p>

<p>Does anyone have any recommendations? </p>

<p>Also, AP tests how long does it generally take to study for them if you want a 4 or possibly 5 if I'm studying for 3 (English and Economics too)?</p>

<p>Never mind. I just realized there are a bunch of threads on this.</p>
