Take two polls online here:
First: Did you go to a top 25 school? If yes, what was your MCAT score:
a) >40
b)35-39
c)33-34
d)31-32
e)29-30
f))<28
Second poll:
Did you go to a school that was not ranked in the top 50? If yes, what was your MCAT score:
a) >40
b)35-39
c)33-34
d)31-32
e)29-30
f))<28
The only problem, people will screw with the data because they think it is funny. but, it might be worth a try.
