From this information, you seem to be on track towards an ATAR in the high 90s range, possibly up to 98.5. Your performance across your subjects is favourable (with some being better than others), the exception being English Advanced.
Mathematics Extension 2 and Earth and Environment Science appear to be your best-performing subjects, thanks to your optimal rank in both. If you also receive the highest HSC exam mark in your cohort for these subjects, they will technically become your overall HSC marks given that you would not be affected by the moderation process in such a position. This also means that there would not be a limit to the mark that you can achieve.
Your performance is also favourable in Mathematics Extension 1 and Biology. Despite the slightly lower rank, you may be part of an academically capable cohort for these subjects and as such, your current level of performance in these subjects would be comparable to that in Mathematics Extension 2 and EES. It is therefore important that you thoroughly prepare for the HSC exam of all these subjects.
On the other hand, English Advanced is your lowest-performing subject and thus likely preventing your performance from being consistent with an ATAR higher than 98.5. This is where there is the most room for improvement. The more you can improve your overall performance in English Advanced by performing well in its HSC exam, the greater your ability to maximise your ATAR, and the higher your chance of achieving an ATAR that exceeds this estimate.
I hope this helps!
