ATAR results are coming up and I have no idea how the offer rounds work. Is main round the first round? If I accept my first offer can I still change my preferences and see if I get an offer for another degree in the second round? Will I lose my first offer if I did this? Someone pls explain everything to me, when are the rounds, etc. My first preference is UNSW so if I get the guaranteed atar am I accepted automatically? Many thanks in advance.
