Ooh didn't think anyone would actually respond!

The social life is really whatever you want it to be. I'd say I'm pretty 'mainstream' in that I was out every night of freshers and pretty regularly throughout all of 1st year, at all the 'popular' clubs. I branched out a bit in 2nd year though, and realised that uni actually consists of a massively diverse group of people with all sorts of social lives, and honestly, whatever your personality is, you're likely to find the right sort of social scene for you.
I don't think anyone HASN'T had to deal with inconsiderate flatmates unless they're the culprit 1st year accommodation can be hard, as it's a complete luck of the draw as to how your flatmates end up. I was lucky, and ended up in a relatively quiet flat with a bunch of lovely girls. Some of my friends, however, ended up with nightmare flatmates. Really, I'd say you just have to stick it out in 1st year, involve accommodation services when you have to (like a friend of mine did), and choose your 2nd year flatmates with care (that's a whole other can of worms).
As for the workload, I'd say it was nothing to me in terms of the jump from high school to uni. I pretty much skim read my notes the week before exams and got mostly upper seconds. However, I go to a Scottish uni where your 1st year grades don't matter and everyone knows it. Making the leap from 2nd to 3rd, where your grades do matter, was incredibly difficult, considering I'd never really learnt to study before. If I'd pulled myself together in 1st year and started uni as I meant to go on (like some of the more self-aware people in my year), I could've avoided a lot of stress and anxiety.
