you can just edit one subjects enrolment for times if you like and i think your original times are saved when you pick SWAP
because when you pick new times and go to continue, a page comes up saying ARE YOU SURE YOU WANT TO SWAP [ORIGINAL TIMES] FOR [NEW TIMES]
If you do not proceed...
Yes, log in and click on student profile up the top
then click on vary enrolment
update enrolment
click SWAP - options are swap and drop
you will need to search for your subject again and add it - then pick a new time. If there is no better time just cancel
** an example of class...
if you didnt get a uac off 2nd round, do you still get a posted letter?
on unsw class utilisation lists - can you tell the times tuts are on, or do you need to go try swap classes to keep checking available times?
