I know this is a late reply, and you may have chosen, but without a shadow of a doubt you should accept Nottingham or Warwick( I had to take a gap year this year to re- apply to similar Universities to the ones you were rejected by( and others) and it’s been torturous-
It feels like I’ve had to do year 13 all over again, and relive that insufferable year- studying for/ resitting the LNAT that could easily go wrong again, edit personal statements, get teachers at a school you don’t attend anymore to sort references out etc… and then spend your year waiting for unis to reply to you-
If you wanted to do a gap year for personal reasons to develop yourself/ a good purpose, it’s a great idea, however if you’re doing so to re- apply to unis that could reject you again, as they’ve done this year, you’d be choosing to put yourself through this hideous system, that just doesn’t work if applying to such competitive unis for such a competitive subject( law)- whilst you already have an offer and a potential offer from two of the best law schools in the UK ( Nott and Warwick)
Save your year or use it for a good reason( not to re- apply) but I would strongly strongly encourage you to accept your Nottingham offer( also- you’re opportunities will be exactly the same whether you go to Nott or a London uni and even Oxbridge for the most part)- I would’ve snatched that offer had I received any in year 13, and I feel it’s important I warn you not to put yourself in this position, whilst you don’t have to( like I did),
Also it feels worth pointing out that people chose to do a gap year to re- apply do Durham, then achieved 3 A*s at A- Level, and were still rejected with an LNAT score of about 25( even though they were achieved grades) so it’s also hugely risky.
I hope this helps and good luck with your choice!
