Son doing 4AS's at top grammar. School (over?) keen that he continues to do 4A2's -- but I think that there is a risk that if he does this he will end up with a mix of A and B grades when he needs 3xA grades for the course he wants to do....and I think he has better chance of achieving this with more focus on each subject.
However do Unis like to see that 4 A2's are being taken even though the offer is for 3 grades....?
If you started the year and submitted your UCAS form with 4 A2's and then dropped one as the year goes on would you have to inform the Unis?
