ATAR scores in the ACT (1 Viewer)

[canberra_guy]

hey was wondering if someone could tell me, someone most likely from Canberra would know, if the grades you get in year 12 are more important towards your ATAR than in year 11, cause obviously year 12 would be harder than 11, so it would have a higher level of importance, riggggghhhhhhhhhhht???????!!!!!!!!!!

also what kind of grades would you need to get an ATAR score over 80, and i know they take your best scores but i don't completely understand what the best 3.6 of your course scores exactly mean, could somebody please explain that to me to make me understand it better? thanks
