Dont worry about not being a drinking or clubbing kind of person, I dont think it has to matter. I go out a fair bit but most of the friends Ive made at uni are on my course, or are interested in the same things as me- I mean Id be friendly with them even if we didnt go out
I think it also depends on what type of course your doing- if you spend a lot of time together with your classmates its easy to make friends there, if your only in six hours a week or something in a class of 300 people itl be tougher
