All our uni visits are waiting until next year. DS3 has been to Warwick quite a few times!
He and I need to wait until we have a better idea of his predicted grades before we decide which ones to visit. It'll almost definitely be for maths which requires higher grades than most other subjects so if he's not on for 2 or 3 x A* there'll be no point looking at Warwick for instance.
I've already been to Warwick, Bath, Exeter, Nottingham and Southampton with DS1 so they may be on our list again for DS3. DS1 also went to Oxford, Cambridge, (school trips on open days) Cardiff and Birmingham. I suspect DS3 won't do quite as well as DS1 so we'll probably have to look at other unis. Maybe Reading, Leicester and Swansea? Avoiding London due to cost. Not thought about looking as far away from home as Manchester, Liverpool or Sheffield etc. though accommodation might be cheaper.
Hopefully predicted grades will narrow the options down to a manageable number.
