Based on this information, you seem to be on track with an ATAR in the low 70s range, that is, an ATAR between 70 and 74. Your performance varies across your subjects, with some being of a decent standard, while others are of a lower standard.
Mathematics Standard, Economics and Business Studies are your better-performing subjects. This means that they are currently making better contributions to your ATAR compared to the rest of your subjects. Favourable performance in the HSC exam of these subjects will help you improve your overall performance, resulting in greater contributions from these subjects to your ATAR.
Your performance is slightly less favourable in Legal Studies. This indicates that there is more room for improvement in this subject, which would warrant the allocation of additional study time for this subject in preparation for its HSC exam. Similar to the aforementioned subjects, the greater the improvement to your overall performance, the more significant this subject's contribution to your ATAR.
English Advanced is your lowest-performing subject, and there appears to be a large difference between it and the rest of your subject. Not only does this indicate that this is the subject where there is the largest room for improvement, but it also indicates that this subject is hindering your progress towards a higher ATAR the most. As such, you may wish to consider focusing more on your preparations for this subject's HSC exam. Ultimately, this would help improve your chances of reaching a higher ATAR.
I hope this helps!
