Nottingham, Warwick and Birmingham will be the hardest for you.
Are you predicted AAA/AAB at A level?
Have you declared your AS grades?
If yes, yes...
If you are predicted AAA then you have accomplished their target entrance requirements. However, you're AS grades will most probably be slightly lower than the exceptional students they will automatically give offers to. Despite this, you are still in with a reasonable chance of an offer. Your personal statement and reference would have to be gleaming, and the spot of work experience might not have gone a miss. It wouldn't do your application any harm at all in regard to Notts and Birm to gain a pretty fab-tastic score on the LNAT.
Chances? Average. Not that great, but not that bad.
Dunno about your other three choices, as I have no idea of repute/applications/entrance grades/anything!
Wishing you all the best with your application.
