I've never done it, but it mostly has cons
First, it wouldn't touch you 3.29 gpa (which isn't bad for DO)
It isn't a true SMP, just a masters, therefore you aren't taking classes with med students, just other master students
A graduate gpa doesn't fix an undergraduate gpa- only post baccalaureate programs or grade replacement can
It doesn't make up for MCAT- only a good MCAT can make up for a good MCAT not a grad program
They say they've put people in Harvard, or something, I'm willing to be that was 1 out of how many. I'm not saying this with intention of knocking the school. I was accepted as well and through this board learned the difference of an SMP vs a masters program and realized I was chasing lightening and didn't need the loans for something that would have a pay out
