<p>This year I'm aiming for 8 AP tests (1 I take at school, 4 I have outside tutors, and 3 I study I my own).</p>
<p>The 3 I'm studying on my own are Calculus AB, Macroeconomics, and Comparative Government. For the first two, I purchased Barron's books. So far for Macroeconomics I didn't find any problems with Barron's (it's not too difficult to understand) but I failed at comprehending Barron's Calculus (and math has always been my best subject). So I researched a little and found out 2 very popular Calculus review books are Princeton Review's and Peterson's. I went to Borders and saw Princeton's and Kaplan's. I chose Kaplan's because it has extra material on how to use a graphing calculator for the exam and the Princeton book does not tell you which part is for BC only, but I can't decide which book is easier to comprehend. Did I make the right choice? If not, which book should I buy? </p>
<p>Also, I saw on these forums that Human Geography and Psychology are the easiest AP tests. Is that true? If it is, then I think I made a mistake in choosing a lot of the harder APs to study? >_> Now I have a urge to take 2 more AP tests (total 10) but I'm not sure if I will have time to study them (I'm completely done with Biology, I'm not worried about the one that I'm taking at school, which is Art History, and I'm in the middle of all the other subjects except for Comparative Government, which I haven't studied yet). The deadline for AP registration is a few days away. Any advice?</p>
