@jimmysmith560 can you help this man out with some better numbers
Given the information in the original post, it seems that OP's current performance is consistent with an ATAR in the low 90's. More specifically, that would be an ATAR of approximately 93.5.
OP's best-performing subjects are Mathematics Advanced and Physics, which is evident because of the outstanding rank in each. Should OP also achieve the highest HSC exam mark within his cohort in both subjects, the moderation process will work in his favour and their HSC exam mark will become their overall HSC mark in these two subjects. This means that OP has an opportunity to maximise his overall HSC marks in both subjects, resulting in substantial contributions to his ATAR.
Although OP's rank in Ancient History and History Extension is slightly lower, his position remains favourable, meaning that both subjects are also likely to make a positive contribution to his ATAR. OP should therefore do his utmost in preparation for the HSC exam of both subjects, allowing him to perform well overall and help maximise his ATAR.
Though not unfavourable, OP's performance in Mathematics Extension 1, English Advanced and English Extension 1 is of a slightly lower standard compared to the rest of his subjects. This could perhaps indicate that there is greater room for improvement in these subjects compared to the rest of his subjects. As such, OP may wish to consider allocating additional study time towards these subjects in preparation for their HSC exam.
I hope this helps!
