The CFA is really demanding (especially level 1) and I think it would be a really difficult thing to double up on. In fact, any other qualification at the same time as business school marks out to be a huge amount of work (I am trying to finish some Treasury exams, but keep on forgetting about them or missing deadlines, and not having time to read for them).
I know there's gotta be at least a handful of FT Stern students sitting for CFA. Do you know of any, and if so, how they've handled it?
I'm thinking as a part-timer, there would be significantly less overlap since part-timers are only taking 2 classes at a time.
