Do Bath Politics and International Relations, actually offer this low (ABB)?

On the open day they said it was AAA-A*AB exclusively.
Contrary to what they said, my offer is only ABB is that actually correct?

Hi,
As far as I am aware, I have no contextual offer whatsover?!
How did this arise then, maybe its because I go to a deprived school in London or is it a mistake?
