It is a hassle, not everyone has the luxury of attending classes that aren't scheduled and wasting a couple of hours of their day.
Oh great, another one.
If you're studying full-time at uni, then you have to be prepared to devote 9-5 to university. You can't go out and get a job during that period and then come on here and say that I somehow have 'the luxury' to do something because I understand what the word 'full-time' means. Do you think you can get a full-time job and say 'well I'm not coming in after lunch if there's no work, as I've got other stuff to do.'? It's exactly the same.
From Monday, semester is full-time, ie even if you have a tute on at 9am, you should go. Sorry, but it's so annoying that so many people at MQ somehow think that they have some right to whinge about coming into uni, doing assignments, not having their ideal timetable, juggling their social life etc, when they signed up full-time. It's obviously the problem of flexibility; people think they're entitled to going out in the middle of the day and having a big job.
Put simply: If you don't want to be prepared to come into uni full-time, don't enrol. It's pretty straight-forward. Otherwise, stop whinging about it and get on with it.
That being said, this thread is made every semester and the discussion always ends up in the same place.
As was said:
Try to find out by emailing the lecturer, looking on Blackboard, or asking people.
If the tute is after the first lecture, then you'll be able to ask then, if it's before the first lecture, it's best just to go. It's really not that much a hassle to go to a tute if it's not on.
Lastly, remember that this is uni. If you don't want to arrange your life, then don't. *shrug*
