<p>I have decided to self-study for this exam and I need to know which book(s) would be the best to study from. I am already going to get the "Smartypant's Guide to the AP Environmental Science Exam" book, but I wanted to see if there are any other books your would reccomend. I want to order them tonight, so I can start studying ASAP. Please respond! Thanks.</p>
<p>i have the PR book...just released last week. its excellent and covers everything.</p>
