no no, ur assessment marks internally in school as well as ur ranks, for IT mean jack shit, its a backup for misadventure, only ur dead set final exam counts, and it is also scaled, this is how it goes, since its only ur exam mark thats counted, thats automatically going to be ur HSC mark, this exam mark is actually scaled by BOS, but then UAC does some nasty shit and scales it down, and this scaled number from UAC is added to other scaled numbers from other subjects to form a Aggregate, which is ur UAI.
