<p>Next year I'm taking 3 AP classes: Environmental, World History, and Calculus AB.
I only have enough money for 1 book per subject, so I'd like to get the most out of each. What are your recommendations? I tried Barron's for SAT Bio, which I really loved, but I understand that the AP exams are quite different. So I'm open to any suggestions! Thank you!</p>
<p>Princeton review for envi science. Crash course for world history. Barrons for calc AB. Well those are my opinions</p>
<p>Cheers</p>
<p>Barrons or Princeton review for world
*barron’s is slightly better organized and has practice questions at the end of each section</p>
<p>Barron’s for AP calc gives you plenty of advice and practice
*got a 5 using barron’s</p>
<p>i used pr for calc ab and bc and got 5s on both tests!</p>
