Hi there, I had to choose between both Glasgow and Edinburgh when I first decided to come to University. My decision being Glasgow. Both are academically as good as one another shown by the University League Tables, so nobody can really say one or the other is better. The students at Glasgow are great in general, however, and I'm sure this will be the same in Edinburgh, there is a small majority who think very highly of themselves, normally posh people who are very condescending, not towards the students at Glasgow, but towards other students at less academical Universities such as UWS and Caledonian.
Help wise, it's brilliant. Glasgow University always has tutorials, workshops, open office hours, etc for any help required, definitely won't be disappointed in that field. The student life in Glasgow is also second to none, the west end is a fantastic place for going out at night whether its to a pub, restaurant or club. Prices are very cheap also depending where abouts you decide to go. I study Mathematics and I don't regret going to Glasgow at all, I just regret my degree choice as the amount of work required is quite intense lol. Hope this helps.
