So I planned to do engineering/commerce at ANU. At first i didn't know what to put in my UAC preference (double arts, business or double engineering and advanced computing) i went to the ANU info day and asked some guy that was there and he told me that if i want to do engineering and commerce, id have to put the double arts, business and social science as my first preference. I did that and got an early offer for it. After that, i checked on the ANU website and it said that i cant do engineering with it only arts and social science. Now i cant change my preferences for the main round and i dont know what to do!! Can someone please help me out?
