Is this the recommended Clif AP Biology?

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
I'm also trying to find out which version it is that everyone refers to. As far as I can tell, it is between the Cliffs AP Biology and the Biology Cliffs Quick Review. Can anyone out there clarify which is the better version or which version they used to prepare?
 
my friend just lent me her copy of jan 2009 version of destroyer. i have april 2008 version, and both of them are totally different.

not only more questions but different arrangements...
 
how many more questions btwn the 08 and the 09, esp. for the bio section?

Have you noticed if the questions are more detailed? Difficult? I didn't know they even offer a class.
 
For those who are using the Cliffs Bio, do you do the free-response questions?
