What happens if you don't get the requested points???Watch
Some unis will take you anyway, especially if you miss by only a grade. I got a B in Maths, and York wanted an A, but I still got the place. It depends on the university, the department, and whether most of the other people offered made their grades or not, though.
If you dont get ur grades then ur well n truly screwed and are going to end up cleaning out sewers for the rest of ur life. Hope my reply makes u feel better
