Grade Requirements?

Hi everyone, I have an offer from Glasgow uni for common law with prediction grades of A*AA, however I’m apprehensive and I think I am more likely to get AAB or ABB. my conditional offer from the uni is AAA. Would I be accepted with grades less than that? Many thanks

Nobody knows. Not even Glasgow uni know. This is because they don't know how other applicants will do.
On results day, the uni will confirm the place of all "firm" offer-holders who have met their offer grades, plus all "insurance" offer holders who were not accepted by their firm choice, but who have met the grades of their Glasgow offer.
If, having done that, there are no spaces left, then you (and other "near miss") candidates will be out of luck.
If there are still some places left, then they'll look to fill those with "near miss" candidates, such as yourself.
How many such places will be available (if any) is impossible to predict.
