How to convince my parents to let me live near campus instead of commuting?

Why did your dad allow you to dorm last year but not this year? It sounds like a financial situation. Students generally get less money if they live off campus than if they dorm, and when you dormed your parents had to pay out-of-pocket. Maybe you should run through the numbers with your dad and see if the aid you were awarded is enough to live off campus. If you get $2400/quarter (I think that’s $800/mo for 3 months, right?) and rent is $560/month, you have $60/week for food, utilities, and entertainment. Are you sure that’s enough?
