Given this information, your performance is consistent with an ATAR between 86 and 89.
Mathematics Standard appears to be your best-performing subject, which is good because it means that it will likely make a positive contribution to your ATAR. You should therefore maintain your effective approach to preparing for the HSC exam in this subject, allowing you to perform well and maximise this subject's contribution to your ATAR.
The same can be suggested regarding your performance in English Standard, Physics and PDHPE, although perhaps to a slightly lower extent. This means that these subjects can also make a positive contribution to your ATAR, the only difference being that you may need to be a bit more diligent in terms of your preparations, and ensure that you address any areas of improvement, which will hopefully allow you to maximise your results and consequently your ATAR.
On the other hand, your position in Studies of Religion II seems to indicate that it is your lowest-performing subject, and may be the subject that is preventing you from reaching your full potential. Based on this, you may wish to consider placing additional emphasis on your preparations for your SOR II HSC exam, which will hopefully enable you to improve your overall performance and ultimately maximising your chances of achieving your ATAR goal.
I hope this helps!
