ANd that makes quitting the job in January in order to start school in September look like kind of a dumb move, no? Why lose out on 7 or 8 months worth of pay, if you're going to delay entry into school? And not to mention screwing over your friend/roommate.
Makes more sense to move home earlier if a part-time job is available (Since he's only working part-time now), the cost of living should be lower so he should be able to put some money aside for when he's studying. also allows him to get settled before the course started and he's not competing for part-time jobs at the same time as the newest influx of students.
