On the radio right now, they are discussing giving preference to students from deprived areas with worse grades than students from good backgrounds and schools.
One "contributor" actually said there was no research that suggested that 3 B-grades from a deprived school was any worse than 3 A-grades from a well-funded school. I wonder why there is a standardised grading system then?
Surely if the selection system is not working, it's better to change your selection system instead of picking and choosing which results of the system to accept.
