Hello Maay, speaking of the message you posted on my profile:
I am actually a VCE student and thus have little idea how your system works. It seems as though you are doing extremely well judging by your ranks, which are quite impressive, especially at a school where your dux got a 99+ ATAR.
I checked Atar calculator and plugged in values for your subjects and it seems as though you would need around an 85+ for each subject to get a 90+ ATAR. Judging by your ranks, it seems as though you are more than capable of doing so. I reckon you should aim for 95+ or a 99+ ATAR due to your capabilities.
