There are more factors to choosing a university than simply the most 'partying' university. How about atmosphere or location or course content? These three, and especially the very latter, can greatly differ at each university and so greatly vary one's wants to go to said university.
My Sociology teacher used to tell me about the wild Sociology parties him and his friends had at Uni.
They all got together and compared Sociology notes whilst drinking wine. He even showed me the Giant Sociology folder he used to bring with him to his parties.
True story btw
also why is everyone saying nottingham? it's nothing in comparison to leeds, liverpool or manchester
Glasgow too, and LSE is surprisingly fun.
A valid question, there are certainly some uni's and cities that have more of a buzz and conversly there are some which are a little more dull.
I attended 3 very different universities and visited friends at many, many others.
Needless to say the rest is only my own opinion.
My first choice would be Sheffield: A lot of student accom. is in very nice parts of the city... Crookes, Broomhill, Hunters Bar, etc... this is certainly not the case in many uni's. It used to be relatively cheap ( not sure how it measures up now); very good student and club nightlife, Easy to get out to country pubs, which with a big group of friends can be great fun, uni union and hallam union both good, a very nice general ambiance.
Second choice: Possibly Manchester. A different feeling to Sheffield, Very good , just different.
third choice: hmmm, Leeds or Newcastle. I used to visit Newcastle rather a lot and never had a bad time. We used to visit student nights and also have a laugh in the townie spots too.
on a different note, and not for the reasons requested in the original...
I must say my favourite university would have to be Cambridge, again a place that I used to visit a good friend at on a regular basis.
