If past HSC cohorts at your school achieved 5-6 band 6's/E4's in each subject (which would be interesting when considering your school rank because this information indicates a potentially rather high success rate that is more consistent with a school ranked among the top 20-30), your current performance would be consistent with an ATAR between 94 and 96. In such a case, your performance can be considered favourable across your subjects, which are all likely to make a positive contribution to your ATAR. As such, favourable HSC exam performance will allow you to solidify your overall performance, because of which you should thoroughly prepare for all of your HSC exams.
However, if you meant that 5-6 band 6's/E4's is the total number of results in the top band, your current performance would instead be consistent with an ATAR in the low 80s range, that is, an ATAR of up to 84. In this case, English Extension 1 and Society and Culture are your best-performing subjects, especially given your optimal rank in each. Should you also achieve the highest HSC exam mark in your cohort for these two subjects, the moderation process will work in your favour, resulting in your overall HSC mark being made equal to your HSC exam mark, and hence giving you a great opportunity to maximise your result in both subjects, and consequently their contribution towards your ATAR.
The same can be suggested, about your performance in Studies of Religion I, although to a slightly lower extent. This means that there is more room for improvement in this subject compared to your best-performing subjects. It would therefore be good to allocate additional study time towards this subject, allowing you to address areas of improvement and have a better chance of performing well in its HSC exam.
On the other hand, your position in English Advanced, Modern History and Legal Studies indicates that these are your lowest-performing subjects. This is where the most improvement can be achieved. You may therefore wish to consider placing greater emphasis on these subjects in preparation for your HSC exams. This is because the more you improve, the higher your chances of a better ATAR.
I hope this helps!
