Glasgow has many English students but nothing on the scale of Edinburgh or St Andrews. The statistics show that Glasgow is actually an unusually ‘local’
university compared to comparable institutions. Partly that’s to do with how Glaswegians are culturally about their city and their university.
Edinburgh and St Andrews are quite different in that regard. People with experience of the universities really notice the difference.
But there are lots of English students there and absolutely no reason why any rUK student should be put off applying to any Scottish university because they’re in Scotland.
The other way round, it does make a difference for funding reasons. As a Scottish student, you’d need a pretty compelling reason to incur huge debts to go to an English university when you could not do so at a Scottish one. That works for students looking at really prestigious courses. Not so much for people considering media studies at an ex-poly.
