SAT II US History Book

<p>Does anyone know what the best book to buy for the US History SAT II exam? I'll be taking the test in May and I want/need to get a 750+ :) Thanks.</p>

<p>Anybody? Please, I need to buy the book today. I would appreciate it if someone could tell me what the best book would be, specifically for the SAT II test. Thanks.</p>

<p>I'm using the SAT II us history for dummies. Usually, when looking for SAT prep books, I just go on amazon and read a bunch of reviews for different books and decide based on that</p>
