<p>Is there going to be a big difference between the princeton review ap physics b book now and the 2007-2008 version? Also the princeton review ap chemistry, will it be different form the 2007-2008 version? I want to buy the books now to start studying.</p>
<p>Usually, Princeton Review just corrects typos and stuffs, mostly minor changes. I’d assume the content is identical. You won’t lose anything by not getting the 2008 book.</p>
<p>Nah, minor changes, the material is the same. The format of the AP Chemistry exam did change though from from '06 to '07.</p>
<p>Princeton review chem has some typos and errors in the answer key for this year FYI.</p>
