What book do you recommend for SAT II U.S History?

what’s a good book to use for studying for the SAT U.S History test?

I am currently using the Barron’s U.S history book. Seems okay.

barron’s is good, but so is princeton review

In my experience, Barron’s is the best. Some of the others aren’t as straightforward (more fluff) and aren’t challenging enough. Is there something about it that’s not working for you? I hear that U.S. History: Sparknotes Review book w/ 3 Online Tests (A,C,D) is a great review too.
