"I wish - it's costing my son £9000 per year for his degree at a UK university."
Well, with all the friends he'll be making it'll pay back in no time. Presuming he's at a Russel group uni, the jobs for the boys should see him through.
If he's not, then I'd seriously suggest getting him onto a German or Dutch university course that's taught in english.
Netherlands is about 2k a year. Germany is free, but you need to prove you can support yourself (~9k euro for a year). Academic entry requirements are about the same as UK universities.
If he's living at home while studying it might be cheaper. But if he's living out, it would appears to be pure insanity to study in the UK. Well, in England. I hear it's still free for Scots to study in Scotland.
