I've taken 1 year of a BA, but now I'm starting Business Administration September 5th. It definately beats highschool, mainly because there's none of the popularity, gossiping, general social bullshit. You're there to study, get the education and skills you paid for, and everything is your responsibility (so punishment for skipping a class).

What I will recommend to nubies is don't ever miss a single assignment. Unlike highschool, you can't afford to just let one go, it'll feck you over good.
Also try to participate as much as possible in class, it'll help your marks in many respects. lol, I was always so introverted in class normally, but if I smoked a joint before class I'd talk the teacher's ear off and he actually loved the conversations I gave him. No idea I was high either haha.
