Data Mining to the Rescue! (Score 1)

I'm a grad student at the University of Waterloo in Canada. Our admissions department uses the past performance of students in their university careers to track back and see what high schools give their students inflated marks. An adjustment is calculated for the high schools that have enough students going to UW to make the results statistically relevant. If you say every potential undergrad is "amazing", but they consistently flop once they get on campus, we downgrade your "amazing" to our "mediocre".
