Majors for Finance.

Yo, I got to the University of Michigan. I did not get into Ross, and in Econ I can't get past a core course needed thats theory, I have taken it twice. Any advice on majors? I currently intern in Private Equity, had offers for S&T at two boutique investment banks and my minor is History of Art. I am a senior and I am trying not to graduate in 3 years, because I am already late and behind. Any advice is appreciated
