My roomate went the the Creighton postbacc. It sounded pretty competitive.......you have to make the grades and also get a certain score on the mcat. If you get accepted to the postbacc, they pay for you to go and do it. However, I think this year, they changed that (you have to pay) and it may no longer be just for minorities. My roomate is asian and I guess that is considered a minority here.
