There is nothing Positive about 'affirmative action'

So the only thing you need to do is prevent corrupt admissions policies. That can be pretty easily prevented by anonymizing the grades. Have a system where the colleges get a list of grades / GPAs alongside a unique ID for each student. The college makes a decision based on the grades, and then after the decision has been made, a computer links the unique ID back to the student's name / address and sends the letter of acceptance.

I know from my experience at least that GPA isn't the only factor that colleges evaluate when accepting students. You have to type up what's essentially a résumé for yourself, provide referral letters, write an essay, and for me anyway as a music major, provide recordings.
