lolz.
Essentially the main rule is no noise after 10pm (so turn off subs/dont talk loudly in hallways etc). Apart from that its just normal laws- don't assualt, dont break stuff etc.
You can get drunk - extremly drunk. But yeah just be considerate of others. You'll get in trouble if you start yelling in the corridors at 4am etc.
However, the college will provide a list of responcibilities that you should abide by. These are things like
* Keeping your room moderatly tidy (some halls have once a semester inspections)
* no fan forced heaters (fire risk)
etc etc Pretty basic stuff that they will tell you about before you arrive. (i wouldnt worry)
Keep in mind you're at uni, theres no major "rules" that are imposed. i.e. you dont have to be home by a certain time, you don't have to answer to anyone if you dont go to lectures (well until the end of the semester when you have to explain the fails lol), and you can do almost anything you want.
EDIT - oh and theres no "role call" or anything. I think the only thing that is compulsery is a 'whole college meeting' that occurs a few times ayear, and even i've skipped a few of them lol.
