Living on campus is convenient, and when it comes down to it, a giant time saver. You don't have to deal with driving, traffic, and parking — instead you can literally roll out of your bed five minutes before class and make it in time to get your favorite seat. It may seem trivial, but chances are that your college days are going to be packed with school, work, and extracurricular activities, so every minute counts.
Apart from getting more opportunities to make friends, living in a student dorm can also be useful when it comes to studying. Still up at 3am and need to speak to someone about tomorrow’s exam – see who else still has their light on! Need a particular book that you couldn’t find at the library? Post a note on the notice board to see if anyone in your dorm has a copy.
