Does anyone have any insight as to why the rankings for MCW dropped so much? I know rankings arent everything, but I am worried because I only have a couple of weeks before I choose my school
Well, do you have a higher-ranked option available to you? If you do, maybe consider it. All I can tell you is what MCW's data looks like on US News, which determines the rankings:
Research Ranking Scores
Peer assessment score (out of 5) 3.0
Residency directors assessment score (out of 5) 3.4
NIH funds granted to medical school and affiliated hospitals (in millions) $99.7
NIH research grant funds per faculty member (in thousands) $67.96
...So they're pretty average on their assessments and their NIH funding is moderate. If you're looking for prestige, MCW may not be the best school for you. On the other hand, if you're looking for a solid clinical program, MCW looks like a great program. It's really up to you.
