not usyd, but it would still be roughly the same amount of time.
that's mine for this coming semester at mq
the standard is 4 units, which normally are made up of one 1 hour tutorial and one 2 hour lecture, of which there are are multiple different times/days depending on the size of the particular unit
its all about what classes you manage to book into on a first come first serve basis, this is the major factor that decides how good or shit your timetable will be,
unless you get some retarted clashes which will normally fuck you sideways
in between classes, eat, work on an assignment, talk with mates, go to a pal session, go to the bar, go to the movies? idk im sure you will think of something to do
also worth noting is most lecturers these days will be recorded, voice only or some are voice and screen capture, you can then download and do at home to save coming in, no idea what this is like at usyd tho.
