look. i hate to break it but the biggest impact on ur English scaled mark, is your English raw mark. not every other course. your 60/100 will also definitley not scale to a 40/100.
ok it doesn't let me use links but search up HSC Raw Database, rawmarks info
you are heavily exaggerating it. additionally, for UAC they also include everybody who dropped out, which means the average is usually much higher.
also. i really do not see the argument towards constantly worrying and stressing about what is going to happen, because that is fully out of your control. even when you get your ATAR, there's nothing you can change. the only thing you can do is how you react to the situation, and where you choose to go from here. if you constantly complain about everybody else and that is the only thing on your mind, that's all you'll be.
there is no reason to complain about everybody else doing bad, when the only reason you would be affected is if you did just as poorly as everyone else. you would not be as affected if you did much better than everyone else... also if more people did very badly in advanced, then your mark in advanced (assuming its not as bad) will scale much better.
it's fine to be upset, but you do not need to take it out on everybody else. i'm sorry if i've been a bit rough, but its the truth. you need to take some accountability.
