Will the edition of the review book I buy matter?

<p>So the 2010 edition of the PR Physics C book isn't out yet...I was going to order all my prep books today. Note that if I wait until it comes out in September it also means I'll have to wait to start prepping for AP Euro and the SAT so I can get free shipping on Amazon...LOL. Also I'm a junior and likely going to take the SAT in december (Maybe January if I wait to order)...</p>

<p>Would it be worth the wait (I can't pass up free shipping lol), or should I just order the 2009 edition now? </p>

<p>Also what usually changes from year to year in the PR Physics book?</p>

<p>Nah. Not a lot is changed. You can tell if the Collegeboard releases any notifications on their Professionals and Teachers site.</p>

<p>Go ahead and order them. I’ll be ordering too… I can’t waste my summer doing nothing. And anyway, how are you going to study if you have other classes and activities to do during the school year? Why not get a head start?</p>
