Using previous year's study notes question, material, previous, unexpected, registered

Greetings all. I just registered for the June 2011 exam. My question is, can the schweiser books from 2008 be used as study material for the 2011 exam?

I ask because in 2008 I was signed up for the exam, but due to an unexpected work changes I basically threw my money away when I wrote Level I. So in lieu of spending another grand on books, I just want to know if I can still get some value out of what I have.

Thanks for the help in advance.
