@fr0z3nst111 --I asked about ACT to find out how well you test. If you can make a 700 GMAT I would hope with your business success they might allow a GPA under 3.5 .
Another very expensive option is the HBS Executive Education certificate program–there is no MBA or other degree granted, but the classes which meet in three week sessions a few times a year are geared to those who already have established companies. (Tyra Banks did the program a few years back and she has no college experience or, I bet, test scores.) You learn the essence of business mangagement, however you can’t call yourself a Harvard grad.
