Schweser CFA Level 1 Study Note June vs December

Does anyone know if there’s a difference between the June 2010 Level 1 study note and December 2010 Level 1 study note? If I happen to fail the June exam, can I reuse the study note for the December exam?

Zero difference. You can reuse them. I have to ask, why’re you thinking so negatively already? You have enough time!
