Thanks for all your help.
My problem is that at Strathclyde this joint degree becomes a 5 year course, while at Glasgow it is still 4. Obviously, this puts more pressure on the year abroad, which might be a good thing or not..?
In terms of courses, I'm confident that both Universities are great, and any professional I have ever spoken to has said that they do not consider Glasgow and Strathclyde applicants to be any different.
