If you achieve overall HSC marks in these ranges across your subjects, you will likely exceed an ATAR of 93. More specifically, performance at this standard will likely lead to an ATAR of around 95.
Generally speaking, achieving an ATAR in the low 90's would require a combination of band 5's/E3's as well as band 6's/E4's. Of course, the more band 6's/E4's you can achieve, the higher your chances of achieving and exceeding your target ATAR. If we were to allocate specific marks that would serve as an example/indication of the marks that you would need for your performance to be consistent with an ATAR of 93 (while being mindful of your own performance potential in each subject), the below may help:
- Mathematics Advanced - 93
- Information Processes and Technology - 93
- English Advanced - 84
- English Extension 1 - 40
- English Extension 2 - 43
- Economics - 84
- Business Studies - 85
As you can see, this constitutes a combination of band 5's/E3's as well as band 6's. The fact that you are taking 12 units means that 2 of your units will end up not counting towards your ATAR. Of course, the above is just an example, and each mark can be slightly different but still lead to a 93 ATAR (for example, you may end up exceeding your expectations in Business Studies, or underperform slightly in IPT).
I hope this helps!
