dude... I seriously would stop trying to figure out what ure gonna get at this stage.. just study ure arse off if your worried about it and make sure your not too pooped to get thru exams. its important to be fresh for exams as well as being prepared.
i mean honestly, ppl who estimate uai's really dont have a fuckin clue what your gonna get, they dont know how much study youve done, what your skool will rank, what subjects scale, they havent even don the HSC.
so stop asking ppl for their opinion, you have a better idea than they do!
