This
would make a great web site. Choose the university you would like to attend , enter your GPA, SAT, race, sex, age and see the probablity (based on historical data) that you would be accepted. See what the answer would have been if you were a different sex. Different race. Different age.
Probably GPA & SAT differences wouldn't matter a lot.
Yeah it would be nice to see it expanded. As it is though it is quite the eye-opener. Did you play with the numbers some?
