Best preparation book for US/World history SATII

<p>I need an advice....In your opinion what is the best preparation book for US/World History?</p>

<p>Thanks!</p>

<p>Last year I took the World History SATII, and I used Barron's to prepare. It was really thorough and detailed, though a bit dense to read. I literally crammed for about a day and a half after just finishing the course and taking my school exam, and I wound up with a high 700s score. No idea about US history. Good luck!</p>
