what Atar can i still get?

[moho65]

I'm currently in year 12 and my subjects are -
Further: average around 93%, rank is about 15/120
Methods: average- 84 %, rank is 9/67
Chemistry: average is 84% as well and rank is 12/58
English (EAL): average is 87% and i'm rank 1/12
physics: average is about 81% and rank 11/35
and I did biology last year and got 33 study score
our cohort is an extremely strong one, our sacs are quite difficult (a little bit harder than the exams), that's why my averages are quite low. I need to get about 40's in all my subjects and about a 45 in further, is this possible considering my bad sac averages? i really believe i could achieve a minimum of about 85% on each of my exams. (I say that in the most modest way possible)
thank you,

i'm only in year 11, and i may be wrong, but i think the sacs mainly just give you your S or N to sit the exams, and it's your exam results that make up most of your study score in year 12. idk, my legal teacher said that we can almost fail every sac and still get a high study score, although, i think that'd be rare. and in year 11, i don't think they scale any scores up/down or assess you like they do year 12. so just work hard in your exams and hopefully you'll be good!

Your sac marks aren't bad for such scores. Just try your best to nail the exams at the end of the year and you may well get an extremely high ATAR
