I agree, quite hard to meet new people especially in those comm lectures, god those things are enormous. Everyone also hangs out in their own little groups, formed of friends from highschool (so do i but want to get to know some new people, instead of those i've known for 6 years). Getting into a sport helps i reckon, you get to meet some interesting people from other faculties and muck around. All in all i reckon Uni is quite awesome, besides a few lectures, god dammit some of those lectures are boring, nearly started bleeding out of my ears during accounting and financial management.
