Also, emergency, MDapplicants.com is hardly a representative sample. Nonetheless, keep imagining that people from crap schools have just as good a shot as admission as those from top schools. It just isn't reality.
First, if you check the posting, I didn't make the MDapplicants comment. I agree, I don't think you can consider MDapplicants a representative sample. Also, there is no verification, so it's hard to tell how many of the "profiles" are even legit. I also don't think that the postings on SDN or, for that matter, here are representative. If you believe the MCAT score thread on SDN, the average MCAT score this year would have been well over a 30 because hardly anyone reported getting under that.
Yes, (for what feels like the 10th time) going to a "top" school MAY give you a better chance of getting in to medical school. And yes, more people from these schools get into medical school than the local state university or small liberal arts college. I would contend though, (and I'm sure you will disagree, which is fine) that this has a lot more to do with the overall quality of students at the various institutions rather than the name of said institution. It only stands to reason that an ivy league school (for example) will have a larger percentage of grads going to medical school because of their student demographic. Just like their average SAT/ACT scores for undergrad will be higher, they will also have higher MCAT scores.
There is no magic formula. If a "crap" school is your only option, then you deal with it and do the best that you can to make yourself an outstanding student with great grades, MCAT scores, ECs and LORs. If having the security of a post-bacc linkage or a well-known name is important and available to you, then do it.
However, for most of us on here, going to a "top" school wasn't/isn't always an option/realistic. I didn't have the undergrad GPA to get into most formal post-bacc programs and I also didn't want to spend that kind of money.
I'm tired of repeating myself on this thread. You aren't going to get definitive answers on here about your chances if you go to X school vs. Y for your post-bacc. We aren't adcoms. Many, many posts ago I advised you to make an appointment with an admissions counselor at a couple of schools that you are interested in attending. These schools are the best ones to tell you how they will view your taking courses at X school vs. Y school and how that will affect your "chances".
