GPA 2.75, Science 3.0, 30 MCAT. Was 4 for four with osteopathic and got into some allopathic. Granted I was a biochemist for three years for BigPharma. When your GPA is low you need a good MCAT and some other things to set you apart. Personally I don't think its possible going straight to med school from undergrad with those stats but i could be wrong.
If your coming straight from undergrad I think it may be tough. I had a 3.4gpa/3.3 sGPA and 24 MCAT [8V,7P,9B] and got accepted to 2 out of 5 schools that I applied. Be it that I was interviewed at both I was accepted at but I did have quite a few good EC's and experience.
This is my advice but if you get like a 30 MCAT [good breakdown] you'll probably have a shot.
Also, if anyone hasn't noticed, osteopathic medical schools are getting more competitive each cycle as more applicants apply with higher stats. But in the end nobody really knows why adcoms pick who they pick.
