I’m going to be taking the CFA Level 1 exam in June of 2009, so I have plenty of time to prepare. I just received my undergrad degree in finance, so I have a pretty focused background on this material.
What study materials seem to be the most useful in preparing for this exam?? Is any particular company better than another? Any strong opinions of buying their flashcards vs. audio CDs vs. computer programs? Any suggestions or experiences to share would be helpful.
