From this information, you seem to be on track with an ATAR of up to 80.5. This means that the upper end of your ATAR goal is definitely within reach, subject to similar HSC exam performance.
Visual Arts is your best-performing subject, meaning that it is likely to make the best contribution to your ATAR out of your subject combination. To ensure that you achieve your ATAR goal, you should thoroughly prepare for your Visual Arts HSC, which will allow you to perform well and maintain a favourable level of overall performance.
The same can be suggested about your performance in Modern History as well as Community and Family Studies, although to a slightly lesser extent. This means that while both subjects are likely to make a contribution that is consistent with your ATAR goal, you may be able to improve your overall performance in both subjects through favourable HSC exam performance, thereby enhancing the contributions of these subjects to your ATAR.
Lastly, English Advanced as well as Society and Culture appear to be your lowest-performing subjects. This indicates that, compared to your other subjects, this is where there is the largest room for improvement. As such, you may wish to consider focusing more on your preparations for their HSC exam to ensure the best possible result and ultimately maximise your chances of reaching (and potentially exceeding) your desired ATAR.
I hope this helps!
