Through SRS I have been advised that I will receive an early offer for my 2nd preference from Macquarie. My 1st preference was UTS. The Macquarie offer will be made on 4 Dec provided I change my preferences to put Macquarie 1st before 2 Dec. Does anyone know how long I have to accept the 4 Dec offer before it lapses? I am hoping that I will have my atar before the offer lapses in case I get the marks to get a guaranteed spot for UTS.
