This is probably a situation you have not heard often. I never finished college, but moved to New York and became quite successful working at international ad agencies and also in my entrepreneurial efforts. At 27, I have more than 7 years of experience working at top ad agencies, have managed international, world-renown brands and manage my own department of 10. I have also started several unique companies, one of which was featured in the WSJ.
If my GMAT score is competitive, and I take some current accounting and statistics classes (and perform well), is there any chance at all that an admissions board would find me unique enough to admit me despite a lack of undergraduate degree?
