Another 3/3 here (~150 hours for each). Did the first two during my MBA and level III after the first year at work. I suppose that, being in study mode during the MBA really helped in focussing on CFA prep. Would be much harder for somebody who is well into their professional career. THAT is truly commendable!
3/3 in 18 months with full time job.

Ok. I did 3/3 but nothing to be so proud of. Luck and some grit, mostly luck.
