BC_MBA_student

I am taking level 2 exam in June 2011. I have read e book version from CFA. I found it very exhausting to read. I'm thinking of reading Schweser materials. Do you think there is significant differences between CFA ebook and Schweser? The poin is: if I only read Schweser, do I have the same chance to pass the exam compare to if I read ebook? Thanks for your inputs. BR
