<p>Hi, I have a lot of tests coming up (AP and SAT IIs), and I'm taking us history and physics b in both tests. I was just wondering if studying out of barrons SAT II studybook for physics b and us history is sufficient enough a review for the AP versions?</p>
<p>Two friends of mine, got a perfect score. They just studied Barron's. So I guess it fairly good. I have heard that Sparknotes is right to the point, still it's Sparknotes. :)</p>
<p>Can't help with USH, sorry.</p>
