Last summer, there was a post a quasi "hypothetical" situation on the internal Yammer forum (at a consulting company for large Federal agencies, VA, and NIH); LOTS of science people work there, lots and lots and lots
Anyway, the poster was saying they'd been accepted to USF - Morsani but didn't want to go there but had no other acceptances and didn't think "Morsani was a very good school have the higher elevated rankings as schools such as Georgetown, Harvard and U Penn" ... In trying to tell this "kid" that Morsani was an excellent school and it was my understanding, the new Dean wanted a median score of 517, that the school would only rise in ranking as the overall school got more research grants, etc.
Turns out, it was the FATHER of the kid... who had a 510 and 3.8 ... that was asking. Kid did NOT attend USF and suspect, will not be going to med school soon. He let the school know 3 days before school started.
No doubt, someone on the WL was overjoyed and overcome with tears hearing from USF that a seat had just opened.
Don't shoot yourself in the foot by rejecting a school because ultimately, if I'm the adcom (and I'm not at any school at any place in any country including the US), I'm going to wonder, "will they do it again to us?" People don't like rejection - students don't, professors don't, and adcom's don't.
