I think you have a point. It's just that I'm a little confused as when I gave UNSW future students a call, and they said that if you don't receive offer for the dec round, even if your uni results are released before 18 dec, you'll still be considered for jan round. But I get your point though, if my score is for e.g. borderline of last year's cut off, highly likely that I won't be considered for the jan round if the cut offs are similar for both dec and jan.Yeah if your uni results are out by say 15-Dec and don't change afterwards, I see no basis for UNSW to reconsider for the January round.
The Dec & Jan rounds are supposed to have the same cutoffs. So is the Feb(interstate) round but sometimes raised even higher - when interview scores of the NSW locals indicate the borderline ones don't stand a chance for an offer, don't fly over wasting your time/money.
