<p>My AP Chemistry teacher required us to get a prep book earlier in this year in order to prepare for a midterm. The most recent version of the Princeton Review out at the time was from 2006-2007. Does anybody know if there have been any changes to the Chem exam's structure, focus, or content since last year? Will an 06-07 version of PR be as effective for preparing as the 2008 version now out?</p>
<p>Thanks to anybody who can help. I tried using the search function and looking at the College Board's course descriptions, but couldn't find the answer.</p>
<p>I don't know what 2006-2007 PR book covers, but I took the 2007 exam and for the first time, these changes:</p>
<ul>
<li><p>instead of like 8 reactions you have to supply the products for given the reactants, you only have 3 (I think) and you have to supply product, balance, and answer a brief question about it (like what is oxidized, reduced, etc.)</p></li>
<li><p>instead of choosing between FR questions, you have to answer ALL free response questions, and each question incorporates material from different "realms" of chemistry</p></li>
</ul>
<p>So the differences are not too significant. And the reactions were CAKE last year; we were definitely over-preparing for those.</p>
<p>Older versions of the prep books are fine. The only changes were to the format of the test - whether you have choice of questions, the length of the sections, weighting of the sections, etc. They were all relatively minor. There were NO changes to content.</p>
