<p>Hi, I am going to take SAT World History and Math Level-1 next year's summer. I bought Barron's prep books for both Subjec Tests. I heard that AP prep books are good for SAT-II Subject Tests...is it true? Does AP World History prep book is sufficient for SAT World History? (I mean the thems are different in APs and SAT-IIs..aren't they?)</p>
<p>Also can you recommend me a good Non-Prep Book for World History other than textbooks?</p>
