This isn't really relevant to your case, but it may help. I'm applying post A-level for Law with Spanish with 2A*s (in Spanish and English Lit) and a C (Biology). However, this is not the first time I have applied to unis through UCAS... I originally applied to study Modern Languages and had a place lined up at UCL but missed my offer and was brutally rejected on results day. (Ended up going to my back-up Bristol but was miserable and left after a term).
I would say... Don't bank on it: Law at Nottingham is very competitive so I guess they can afford to reject anyone who misses their offer. I speak from experience when I give this advice; I banked on it! Unfortunately for me (as a results day reject), UCL is so competitive and prestigious that they can afford to be harsh and are harsh indeed. I assume it's the same (or similar) with Law at Nottingham.
However, that (stuff about UCL) being said, I called up admissions at Nottingham before I applied (this time round) to check that they would actually consider my application with a below par grade, and they told me that they operate a flexible admissions policy. With that in mind, I suppose the likelihood of them taking you with A*AB instead of AAA all depends on how MUCH they liked you and the other aspects of your application. Obviously it's impossible for you to tell how much they liked you. Which is why you shouldn't get your hopes up.
PS: sorry for the long post... It was a long story
