oh hey kids i'm helping out at o-week, don't worry i'll tell the EU people to leave you alone
and seriously there is nothing to worry about.. basically right now you just do your exams, and then after you finish you have like a month to stress out and change your preferences everyday. and then you get your uai in mid-late december, and get to stress out till jan 5 when you go to uni open day to ask about courses. then you finalise your prefereces that day. and get another 2 weeks until you get your offer.
and then you get another month until o-week
seriously about 4 things happen over the span of 5 months, you'll be lying on the couch all day everyday it's not like you'll forget to enrol because your schedule is so full
