<p>I hear about this book, and I have it myself, but I find that it's missing quite some information that AMSCO contains, and it seems to me to be very short and concise.</p>
<p>Has this book + AMSCO actually helped people?</p>
<p>It's impossible to memorize all of AMSCO, so I'd imagine REA helps to remember the important things and AMSCO helps set the background. Is this correct?</p>
<p>Most people recommend AMSCO only as it will suffice for the exam. </p>
<p>Of course if you want to be absolutely sure of scoring a 5, then you can get AMSCO and REA.</p>
<p>That’s what confuses me a bit, REA Crash Course is such a simple resource… how can it assure a 5?</p>
<p>I used AMSCO + REA + Kaplans SAT II USH for a 790 on the SAT II (so I got like 81/90) of the m/c</p>
<p>I think that same combination would work wonders for the AP test as well</p>
<p>I should add that I never took AP USH</p>
