i was gonna say..... i dont like that word "randomised" in that quote
how often do ppl have 8am classes?
I've never had an 8am class... if I did, I wouldn't turn up.
There aren't many for Arts or BusEco students, and rarely do students get stuck in them unwillingly.
There are more in areas like Engineering where these options must be made available since there are higher contact hours.
(higher contact hours = more classes = more clashes .: more options that are unlikely to clash are needed)
If you lurk often enough on Allocate during adjustment mode (think: refresh, refresh, refresh, refresh) you can usually switch into your first preferences.
"Randomised" is just their way of saying that there is no bias when they allocate your timetable... the fact that one person gets into a class while another doesn't is random luck... there is no conscious decision made and it's not something intentional.
Edit: Wait... I lie... I've had two 8am classes... there were two early-morning computer lab classes I had to attend for Japanese... I did actually rock up to them... it was a miracle.
