America's best Black Colleges. Spellman was number 1!
I went there from 78-84 (undergrad & med school) and loved it but its SO much fun it can be hard to graduate.I'd say it was largely middle class black folks who had often excelled where they came from. Men are "underrepresented" at most schools, I believe because the current school system doesn't play to their strengths. I think statistically men make up for it with the SAT's. Unfortunately this is not true for Black men.
