Make everyone take a PLSAT test to weed out those who are unlikely to get a good score.
Blacks are scoring lower on these standardized tests because the applicants are less qualified than their non-black peers. The real problem is that the flaw in affirmative action is exposed; once you admit unqualified students and they can’t get a job after the years (and money) of school, you end up with unemployable, indebted angry blactivists.
