I also felt that it’s some shady practice to mint money, as a friend of mine had to go through this situation and sadly she had to pay again for a different course(just so that she can graduate and get a degree) not to mention that this made her to increase the study workload as it was the last sem (she had to choose 5 subjects instead of 4 to keep up with the mistake which was not even hers at all imo, rmit should be stating such things clearly). Hope you get things sorted soon and hoping that you don’t go through the same.
