From this information, you seem on track with an ATAR between 89.5 and 91. Overall, your current performance is consistent with the lower end of your desired ATAR range, and that is a good start.
Chemistry and Mathematics Extension 1 are your best-performing subjects. This is because you are ranked first in both of them, meaning that if you also achieve the highest HSC exam mark in both, you will be able to maximise your HSC marks in both, allowing both subjects to make a significantly greater contribution to your ATAR, potentially bringing you closer to the upper end of your desired ATAR range. You should therefore thoroughly prepare for these subjects' HSC exam. Your HSC mark in Mathematics Advanced is very good and will also make a positive contribution to your ATAR.
The same can be suggested, although to a slightly lower extent, about your performance in PDHPE. This means that your ability to maximise your overall HSC mark in this subject will be slightly lower than the aforementioned subjects given your rank, although you can still achieve an outstanding result through favourable performance in your PDHPE HSC exam. Your HSC mark in Studies of Religion I can also make a good contribution to your ATAR. However, it will likely be lower than that of Mathematics Advanced.
English Standard appears to be your lowest-performing subject, indicating a greater room for improvement in this subject. Based on this, you may wish to consider focusing more on this subject as you prepare for your HSC exams, which will hopefully allow you to improve your overall performance in this subject and maximise your chances of reaching a higher ATAR.
I hope this helps!
