Don't be too late or you might get a detention.
But as has already been stated, tutorials are your first priority, lectures last. People will understand if you're late since not everybody has a perfect schedule.
It sucks eh. My semester 2 is still messed up with lots of gaps. I haven't decided on my fourth subject yet, since I've got to bring something forward from second year.
Have any of you enrolled for Engineering Practice Preview 1?
edit: check out my sexy new timetable...
I thought it was gonna be bad, but I managed to clean it up so not much of a difference. I'm in the city on tuesday nights, so that 1 lecture won't bother me.
