<p>What is the difference between editions? I have only been able to acquire the 2009 edition (or the 8th edition, not sure). Do you think this will have outdated information? </p>
<p>I also have the Princeton Review 2012 Chemistry book, however.</p>
<p>ColdFlame- I studied from Barrons for chemistry…and I just gave my SAT II on the 28th of January…and I found the test REALLY easy! But I heard Princetons the best so I don’t know…I’d definitely recommend Barrons :)</p>
