I graduated from city about a year ago. Did computer science there.
People were friendly. However I found that most of the people just gathered into groups of their ethnicity/nationality, like if someone was from russia then they would mostly hang out with other russians, that sort of thing or like form groups with people living in halls. I didn't find that many interesting societies to join and like there's muslim society, bengali society, greek society etc. and I'm neither of those so I just didn't join any. In terms of like events and stuff, I either didn't hear about them or there actually wasn't that many.
What else, you'll also get a personal tutor when you start, however I found him kinda useless like I barely met the guy and all advice he had was to refer me to somewhere else like student centre, so I just went directly to someone and forgot he existed and he forgot I existed as well.
Modules, some were really great, some were really bad like the lecturer seemed like he was in wrong place other modules were alright (because the subject was quite dry like Object oriented programming can't image someone actually making it a thrilling subject)
A lot has changed though I think since I graduated, however for 9k a year that they charge now, I don't think it's worth the money. I'd probably go somewhere else maybe even different country for uni if I had to choose again.
