<p>do i have to or should i buy a book for the sat 2 us history test if i already have 2 AP test books for it? I mean, the AP test and the sat 2 test should be rather similar right? except for the essays?</p>
<p>Correct. I used my AP book (REA) and did well, so your AP book should be fine. The tests are similar, but the SAT II is a bit easier, and there are some trivia questions. A question on my test was who was the first female vice-presidential candidate? There are questions like that, which require pure trivia, unlike the AP questions, most of which require complex thought.</p>
