Simply because passing your MBA is more of a certainty, do the MBA. Do your CFA after your MBA (if you still have the stomach for it that is). It's not uncommon for MBA grads to take CFA later, esp. if they are in the relevant industry.

Hey guys,

I've been toying with the idea of taking up CFA but I don't think I'm quite ready to sit for the Dec or June2013 Level 1 exams as yet due to personal reasons (i.e. no time to focus on CFA).

But I would like to go thru Level 1 materials so if anyone wants to get rid of their Level 1 books/study materials I will be more than happy to take them off your hands.
