A guy from my grade in year 11 had worse grades than you and still got a pretty offer from wollongong. Other people who in my grade who got around the same grades with similar subjects got offer from macquarie, though they did some prefect stuff or something along the lines of that...
Dude I remember some people in my cohort who started off in similar situations to you and put in decent amount of effort and managed to get by with 70s to like 80s atar. I say cause like their subjects don't scale as well as yours do so I think you getting 90+ atar is achievable as long as you...
