REA U.S. History AP vs. SAT II Book

<p>So in preparation for the SAT IIs in US History, I managed to dig up the Kaplan book and the REA AP Book. Of course, note that for REA I found the AP book, not the SAT II book.</p>

<p>So my question is, will I be okay prep wise with the REA AP US Hist book or should I go out and buy the SAT II one? I'm not particularly concerned about the practice tests that come with it, as I have those in Kaplan, but I want to make sure I get all the right material.</p>

<p>Thanks in advance.</p>

<p>REA is perfectly fine; I used it for the SATII exam in May.</p>
