Hi all, not sure if this should be in the VTAC section, but figured it'd only really be relevant to current uni students... Apologizes to the mods if I got it wrong

Basically, I've completely changed my career aims this semester (Actuary -> Engineer), and made a rash decision to pay the VTAC fees before the timely application closed. However, I've now come to the conclusion that my best bet would be to complete the BCom + DMath and do extra physics subjects through CAP, then do UniMelb's 3 year masters program.
I went to the relevant AskVTAC section online, and it said "Fully paid course applications cannot be withdrawn and are non-refundable (except as required by law). If you are made any offers you are under no obligation to accept them and not taking up an offered course will not impact negatively on any applications you may make in the future."
Probably a silly question, but since I only have Monash and RMIT courses in my preferences, if I receive and reject an offer from one of these, this won't affect my UniMelb BCom enrollment right?
Thanks everyone
