If you're dedicated, anything is possible. People commute from as far as Springwood, Gosford and Campbelltown to uni. Obviously try to customise your timetable so you have to come in on as little days as possible. If there are lecture notes posted up, that makes it much easier to skip, otherwise, if you have a lecture where there are no notes provided, make your tutes on that lecture's day so you're not coming in just for one lecture.
