The really good post-bacc programs are really as hard, or harder than to get into med school. They are looking for people with excellent GPA's, but non-science majors, some want good SATs, plus some clincal volunteer work to boot. I know the Goucher program in Baltimore get something like 700 apps for about 30 spots and JHU which just started has similar stats at this point. But there are some that will let you enroll if you meet their minimum criteria if you can foot the bill. O applied at the above mentioned programs with over a 1400 SAT and a 3.3 GPA from a top music conservatory and while I got interviews, I didn't get into either to give you an idea. They aren't looking for people that need to bring up their GPAs, they're looking for people that need to complete the pre-reqs and already have a stellar background. I was definitely hurt by my lack of clinical experience. Goucher's program boasts an overall admit rate of something like 95% and no one in the past few years hasn't made it as I recall, so you can see the standards are pretty high. I think with having to bring your GPA up that much to be competitive for admission to med school, if possible you should try to get into your state school if it's good and if they're big they often had a post-bacc pre-med advisor and it will save you some money since med school is hellishly expensive. You'll get all the benefits of being a regular pre-med student atthe school, and while it will probably be harder to gain admission this way, I think it's a good alternative to the private programs that will admit anyone if you're not able to gain admission to the really good post-baccs.
I hope that didn't come off as harsh, but I'm going through the same thing!
