Any Rec for SAT II US History Prep Book?

What is it that you used? I want to get a 800 in the sat thing and I have got a 5 in the AP. My teacher wasn’ that strict so I actually didn’t read the most part of the American Pageant book, just using APnotes haha! but still I think the notes for SAT is sorta different so I wonder your opinion on some of the best prep books for this thing.
