How do I convince my parents to let me dorm?

Why do you think commuting is not part of the “full college life?”
Commuting to college is the [norm[/url], not the exception.
40.6% of 4-year schools are [url=http://digitalcommons.uri.edu/cgi/viewcontent.cgi?article=1233&context=oa_diss]primarily nonresidential](http://www.nsse.indiana.edu/pdf/commuter.pdf).

You might convince them if you could pay for it yourself. Keep in mind that if you get a job that will take up time just like commuting will.
