Best books for AP: spanish, bio, psych

<p>we get barrons AP bio with the course but is that book really good enough?</p>

<p>and my teacher suggested REA for AP spanish.</p>

<p>idk about ap psych though?</p>

<p>and suggestions?</p>

<p>For AP Psych last year I used a Kaplan book year 2009/2010 and I got a 5 on the test. I also used all the other materials my teacher gave me though.</p>
