800 US HISTORY - Absolute Best/Most Reliable Book?

<p>Hey guys! About 2 weeks until the subject tests. I want to know what SAT 2 Prep books for US History can guarantee me a score of 800 if I thoroughly study it. Much help appreciated! Pros/Cons of the recommended books help too!</p>

<p>AMSCO. and are there any other good books?</p>

<p>I second AMSCO. It’s the best for AP US History and for the SAT II. I’d also recommend Crash Course for review</p>

<p>REA Crash Course in APUSH was an absolute godsend for getting me an 800 many months after I was even in a history course.</p>
