Will Notts still accept me?

So I received an offer for criminology and sociology for BBB even tho the typical offer is ABB.

I will try my hardest to get these grades, however, if I fall short of one and get BBC would they still let me in do you reckon?

I know BBC is one grade off my offer but in hindsight it's TWO grades off their original entry requirements.

I need peoples opinions thank you !
