According to my trusty dusty MSAR, Boston takes people past high school.
But these programs are for super uber ultra overachiever Doogie Howsers. If you already have a college record, particularly an unclean one, I don't think they're interested. To get into these you have to have already demonstrated that you're MD material. Based on your previous posts I'd guess you're looking for a program where you can prove you're MD material. Such as a normal undergrad re-entry.
