Is that all I need to do for now? I can just choose my proper subjects in February right?
As long as you've got 8 "subjects" enrolled, i'm pretty sure that's fine (taking into account required credit points for science subjects and breadth subjects) . You can withdraw and replace subjects over the summer holidays no problem. If you have any subjects that have quotas, i'd try to enrol in those as soon as you can.
Take note of these dates too:
Last date to enrol in standard Semester 1 and Year-Long subjects Friday 13 March
Census date for standard Semester 1 subjects (last date to withdraw without incurring a withdrawn comment and a HECS-HELP/FEE-HELP/Fees liability) Tuesday 31 March
Thanks to everyone for all the help this year. This thread/forum really contributed positively to my jaffy experience (every single one of my questions were answered so quickly here!) and just seeing you guys talk about your own problems/experiences helped me learn a lot.
I'd like to second this. There's no way I could have been accepted into my postgraduate course without the constant university/subject advice I have received over my undergraduate years.
