I don't know if a link for this has already been discussed on the forums, but I just came across it today and thought it was a thought provoking and insightful discussion of the US News rankings of medical schools between the publishers of said rankings and several Deans of the top medical schools in the country. They touch upon several of the subjects which are so often discussed on these boards including medical school prestige, the importance of the MCAT, variability of GPA between different colleges and different majors, research, diversity, among many other topics. It is quite long, the pdf is 66 pages, but a lot of good info if you haven't seen it yet.
