You dont need 90+ in every subject in order to get a 90+ ATAR. With your subjects, I reakon you could maybe scrape a 90 ATAR with a combination of mid-high band 5'sis it possible to get in the 90s if i got band 5s and 6s in the HSC?
I'd say its very unlikely given your ranks. However, ATAR estimates are very unreliable, just try to keep that in mind. For all we know those ranks could be enough to get you to 96 - but I doubt it.would it be possible to get a 96?
