Study at least every week. If you ever catch yourself feeling bored try to use that time to study you might as well.
Go to tutoring if they offer it really helps if you can't seem to study by yourself.
Talk to people. I still have this problem of not talking but if you have any questions ask them.
If you're taking any general math classes and the texbook and professor suck, Youtube will become your best friend. Also ask like I said before. Also always do math homework or problem questions. It helps.
Rate my professor can help if you're looking for good profs.
I don't dorm so I don't have any tips for that.
