phys b barrons
human geo barrons</p>

<p>now, the human geo 2008, the chem 2008 and the phys b 2008 come out in january or something… whats the difference between these 2008 versions and the normal ones? the book i need the most is chem what is the differece between chem 2008 and chem 2006 - 2007?
how much time do you really need with a prep book to get a 5? is four months enough?</p>

<p>I think 4 months is plenty;correct me if i’m wrong, but I think they changed some minor things on the AP Chem exam. Pay attention during the year and you’ll do fine on the Chem Exam - It has a pretty generous curve.</p>
