<p>I have a questions, I'm taking AP U.S. History and AP World History and next year and plan on taking the SAT II Subject Tests in those two subjects at the end of the year. To study for the AP exam.subject tests should I buy a book for the AP exams, the subjects or both? Also, what book should I get for the Math subject test?</p>
<p>Your AP exam books should be good enough for the subject tests. They ask similar questions.</p>
