<p>I recently purchased AP test prep books in anticipation of the exams in May, and of course neglected to check College Confidential for advice until after my trip to Barnes & Noble. Today, I discovered a thread with specific suggestions for review books. Can anyone offer insight as to what makes a certain company's review book preferable to another's?</p>
<p>For AP Euro, I purchased the Barrons guide (CC suggests Modern European History), for AP USH I chose PrincetonReview (instead of CC's Amsco), for Human Geography I have REA (instead of Barrons), and I believe that my Calc AB teacher bought us all Cliffs review books (instead of Arco). Does anyone have experience using any of these books? Should I return my purchases and look for the others instead? Since I am self-studying Human Geography, will the type of book significantly effect my score, or are time and dedication more important? </p>
<p>Any advice or insight would be very much appreciated! Thanks in advance.</p>
