Our English teacher told us all about this and it seems quite strange. And like Limey said, racism in reverse. I don't know, i understand how hard it is to combat such a turbulent history but if i was a black student i would feel as if i was just getting a place at uni because of my skin colour and not because of my own merit.
A similar thing happens here where universities have been told to take more state school pupils in so people are moving from private school to state school just to get into good universities, state school students feel like they have only got into Oxford because they didn't pay for education.
