When OB was a poly, it's only campus was at Wheatley. Now there are buildings and courses in Headington which is much closer to the city centre.
Completely OT (but since when does that matter on MN!) but I'm procrastinating over an essay and was mildly intrigued as I've been to a couple of OU classes at the Brookes Headington campus and it seemed pretty well-established.
Anyway, the above isn't true
They did have loads of little schools all over the place, moved to Headington in 1949, became Oxford Poly in 1970, and acquired Wheatley in 1976 by taking over a teacher training college.
Re choosing universities -
I think subject has to come first, before course specifics, or the location/character of the uni. It's up to the individual which is more important to them, the nitty gritty of the course, or what their university's like. But surely not many people pick a uni then look for subjects offered at that university?
If the OP's ds has no real idea at this stage what subject he's interested in, then I would suggest either looking at Scottish universities where you can do 3 subjects in the first year, wide-ranging courses (except I think that e.g. the Liberal Arts courses have quite high entry requirements), joint honours courses, or a gap year.
A lot can change in 6 months though, if he's keen enough to start looking and reading. There are open days in June/July (and some do get booked up quickly, but most will be ok. And then nearly everywhere will also be having open days in September/October too - for most people there is actually a lot of time left before next January.
Right, back to the essay I'm supposed to be writing!
