<p>I heard REA is good, but isn't that just for APUSH?</p>
<p>Not really, I’d think APUSH (the class) or just studying through an APUSH review book should prepare you perfectly for the SAT II. It’s multiple choice anyway, so there’s no concept understanding type stuff to know for say, the APUSH open-ended/essay stuff.</p>
<p>AMSCO AP US History is awesome for the subject test.</p>
<p>It’s about 700 pages so be prepared to invest a large amount of time into your prep.</p>
