I've already recieved 3 offers from usyd, unsw and mq. but after considering for several days, i've changed my mind to choose another course in unsw which was in lower order in my course pereference, so i changed the order and deleted the one i've already got offer from unsw. i'm sure my atar is good enough for my new course, about 6 atar higher, but there is no another offer sent to me. could anyone tell me when can i get my new offer...thx a lot!
