Raw HSC marks needed for a 90+ ATAR? (1 Viewer)

[luo_ge]

I've finished my internal assessments and I go to a school usually ranked between 30-40.

My ranks are (approximate since not given back yet):

English Advanced: (bottom 40%)
Chemistry (bottom 40%)
Economics (middle of cohort)
Maths (2U) (top 30%)
Maths (3U) (bottom 20%)
PDHPE (top 20%)

Is it still possible for me to get a 90+ atar since the actual exams are worth 50%?

What approximate raw marks would I need to get an atar of 90+?
