<p>Order this online: Amazon.com:</a> The Smartypants' Guide to the AP Environmental Science…</p>
<p>Read through it two or three times before the exam, do practice FRQs online, and you'll get a 5. SUCH a good book. So CONCISE yet EXPLANATORY. Really. I got a 5 on it this past year. Don't waste money on textbooks or Barron's (ESPECIALLY BARRON'S).</p>
