I really don't know but here we go:
Standard Eng: 82
Math Adv: 95
Math Ext 1: like a 37/50 (idk not expecting much)
Chem: 84
Bio: 90
Music 1: 92
Atar prediction: hopefully just 90+
I would say prob because the people who do Chem/physics tend to be good at the subject whereas a lot of people do bio because it's the "easy science" and then don't realise the effort it takes to get higher marks. Just my theory on it
For Chem you are only tested on mods 5-8. However, you may have to use the skills/formulas that you learn in year 11, such as n=m/MM , C=n/V etc. This year in particular, many of us had to use the PV=nRT formula, despite it not being mentioned in the year 12 syllabus.
School rank: 200-300s
Ranks:
None of my subjects got band 6's last year (perks of the school rank 😍), although typically we get at least 1 per subject (other than chem and music).
Subject Averages:
English Standard: 80%
Math Advanced: 91%
Math Extension 1: 78%
Biology: 78%
Chemistry: 80%...
