Get a job

Find work on campus, if you can. Departments expect their student employees to have screwy schedules so there's no drama if you have to work two hours here and three there to get your week in. If not, try to find something that'll help you out in your career. The experience will help set you apart from all the other grads when you finally get out of school and have to get a job. You won't believe how many people have zero experience when they collect that degree.
