Well done on your offers! But as already mentioned please take your time deciding - these are very different unis!
Manchester, Leeds and Newcastle are big, city universities, right in the heart of everything. Comparatively, York and Exeter are smaller, campus unis (for reference, I’m at york.) so that’s gonna be a big difference you should consider and would really be worth a visit I say.
Also for law, really look at the course - I know at York we do PBL and have a PBL suite and all that, so worth considering if the other unis learn like that and if that’s how you want to learn.
