I volunteered with one young woman who got accepted to an expensive school in the city. She said she was going to commute from the suburbs to save money. I thought she was nuts. Sure enough, I met her roommate at the interview a year and a half later. They were living not too far from the school. Clearly, she couldn't or didn't want to deal with the commute. Clearly it's possible, but do you really want to face a one hour commute after studying for nine or ten hours?
