Hi There!
I planned on buying a secondhand Schweser module from one of my friend that took the test last December, I believe the book is stamped either in 2007 or 2008. Is there any difference between that book with the newest Schweser book in term of relevance to the 2009 CFA Curriculum?
Thanks for the answer
