From this information, your performance seems consistent with an ATAR in the high 70s. More specifically, that would be an ATAR of up to 78. The level of your performance varies across your subjects, although it would be reasonable to suggest that favourable HSC exam performance will be crucial for you to achieve your 85-90 ATAR goal that you mentioned in your earlier thread.
At this stage, your best-performing subjects are likely Mathematics Advanced, Studies of Religion I and Enterprise Computing. This means that they are likely to make the most significant contribution to your ATAR compared to your other subjects. It is therefore important to perform well in their HSC exams so that you can further improve their contribution.
You are performing at a slightly lower level in Biology and English Advanced, which is an indication that there are slightly more areas of improvement in these subjects than your better-performing ones. As such, you should focus on addressing them as you prepare for your HSC exams, which will hopefully allow you to improve your performance in both subjects and maximise their contribution to your ATAR.
On the other hand, Mathematics Extension 1 appears to be your lowest-performing subject. This means that it is likely the subject where there is the most room for improvement. Thorough HSC exam preparation with a focus on addressing every weakness/area of improvement will hopefully allow you to improve your performance in this subject and, by extension, its contribution to your ATAR.
I hope this helps!
