<p>I just finished the Princeton Review book, and it was Ok; couple typos, and the tests seemed easy. If I were to buy another prep. book, which would be better, Kaplans or Barrons?</p>
<p>Sparknotes. Do it. Automatic above 700. (well, maybe)</p>
<p>The sparknotes book is online, for free (sans practice tests, but I think you can at least take one or two online for free, I'm not sure). I can't vouch for chem, but for Physics Sparknotes was my exclusive source (I hadn't even taken the class) and it was good enough for an 800.</p>
<p>I used sparknotes for physics, chem, and math II, worked like a charm.</p>
