Uni is lots of fun!
It really depends a lot on your course, more on your subjects, a lot on your university and their union, but mostly on you and what you make of uni.
There're so many people, so many things to do at uni... there's everthing... No one's pushing you around as at school... You can sort of be as lazy or as bothered as you like... You can miss classes and no one care, but sitll get the course done if you decide you want to... And there's no one pushing their message upon you like there might be at school (actually, that's a lie, there are plenty at uni, with their flyers, but they have no say in what you do)...
But they're really different things to compare. You miss your school friends, especially if not many go to your uni... Maybe you miss having a simple life. You don't miss the HSC, but you start to learn when to stop and put an effort in because you do have to pass an exam, if not learn, someday....
