US History for Dummies

<p>I picked up this book at the thrift store for a buck or two. It's not the sat 2 specific one, but the regular one (it's from 2001, so... pretty old :/). I took regular history (not AP) last year. Do you think it would suffice for the subject test, or should I invest in a review book. If so, which one?</p>

<p>would i be better off getting a newer review book?</p>
