You get fully catered halls too. It depends what he wants really, and how well he can cook.
I'd say that he (not you) should look at the prospectuses for as many universities as he's interested in, and that he should be going to open days on his own (although I realise that isn't necessarily practical if he's looking at Aberdeen and you're in the south west).
He needs to think about:
- The degree course.
How is it organised, and how will it be taught? There can be a lot of variation in this and it may affect how he feels about the course.
How much flexibility is there to choose outside subjects and options? What are the specialist areas within the department? For example, a politics department may have particular expertise in American politics or European, or they may have a focus on community politics. This will all affect what topics will be offered/focused on within the degree.
What do the current students think of the course?
All universities participate in the national student satisfaction study every year, and you can find out the score by department.
How well regarded is the department in the particular field?
And, of course, check the entry requirements and how difficult it is to get a place. Some universities have ridiculous numbers of applicants per place, and some discipline are especially competitive. When he applies, he's probably best thinking about at least one back-up option, especially if he's applying to hard to get into courses.
- Where the university is.
He'll have to live there for three years, so this matters. It's no good going to hull or Southampton (for example) if he's going to hate it there. It's worth finding out about how much it'll cost to rent a room in a flat after first year too, as this can be enormously variable and will affect his finances and experience.
- extra curricular activities
Is there anything he'd like to do while at uni? Does he play a particular sport or participate in some kind of club? It's important that he finds out about the opportunities he'll have to pursue his interests, and to develop others. The uni websites will have information about sports facilities, clubs and societies and other things that aren't academic but still matter to how happy he'll be. This is really vital as miserable students do not do well.
- The university more generally.
It's worth funding out about study support available and the personal support systems in place. Universities vary in the kinds of pastoral care provided, and this really matters.
But, as I have said, it's up to him to find all this out and decide for himself. You have to let him get on with it.
