Using previous year's study notes

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.

I would just get new books. ive heard there is about a 15% turnover of information YOY (heard that from head of exams) so there could be a lot that has changed since then. The worst thing you could do is throw away your money again because you used old books.

There are a lot of changes for 2011. Get new books.
