SAT does not grade anyone easier.
You mean they won't admit it but they do. Blacks get a huge break on the essay test since there are no "right" answers and the score is a judgement call. That's the idea for the essay test.
Whites do much better than blacks on the essay test dude.
Try again, next time with some proof and maybe some facts.
If you do not have any just make them up as you go.
