<p>I will be going into senior year next year and considering getting a head start on AP calculus, chem and physics. I know I won't be able to get that far but just a brief overview of what is to come, as I will be taking all three of these courses in school next year.</p>
<p>I have done some research on prep books and came to the understanding that the 2014 prep books aren't out yet. (at least for Princeton Review) I know Chemistry is changing so I would have to wait for a new edition, but for other subjects, is it better to wait for and buy the new edition or will the older 2013 edition do fine?</p>
<p>I'm considering Barron's for calculus and chemistry, Princeton Review for physics B. Does anybody know when the new 2014 edition will be out?</p>
<p>Thanks.</p>
