Although I agree that the Econ and Calc grades would not be at Ross expectations, you should try. Most importantly, you can be a successful business person and meet your career goals without going to Ross. I am Chief Operating Officer of a substantial company and I have a undergraduate degree in Liberal Arts. I know many executives with Liberal Arts degrees. Don’t give up on your dream! 3.5 at a phenomenal school like Michigan is a solid accomplishment! Good luck.
