You’ve picked a whole range there — ones you’ve mentioned like Warwick and Leeds are pretty competitive to get into, Nottingham Trent perhaps less so.
Like others have said, it’s very much grade dependant. If you’re looking at A*AA, then Warwick, London ones, Oxbridge, Bristol etc are worth eyeing up, while if you’re going with CCC, you’ll need to look on the lower end of the spectrum.
