What do you usually do when you are in university or college?  

I amstill in school so i cant tell my experieces but i can tell my bro's experiences..he used to wander here and there in his collage...In hostel he used to start his laptop and open arsenal Fc community in orkut 24x7 . when i went to visit his hostel. his friends were half naked ..They used to paty alot during nights . i don't think my bro ciagrettes ..but his mates really do . In the mormings he used to practise soccer and go to the gym for his fitness. AFTERALL he is doing marine engineering

There are a point in my college life that I experienced what your experiencing now. And the result I failed 2 of my major subjects which caused me to graduate 1 semester late. For me I just need to set my priorities right. And studying should be the top priority. Of course don't just study because that will make your college life boring. You should get out, have fun, play games, etc.
