To clear up misconceptions perpetuated by certain tutoring companies, standard scales EXACTLY the same as advanced i.e. a 95 in standard will give the same ATAR boost as a 95 in advanced etc etc. Theoretically, these respective marks require the same English ability to achieve. However, their
alignment is different. You will need raw ~81 to scrape a 90 in advanced but raw ~88-89 to get the same 90 in standard. This 90 scales exactly the same tho. Whichever one of those marks is "easier" for you to achieve is up to you. However, standard historically gives out very little band 6s so you might have more luck in advanced.
95 HSC mark in Standard English would be top 3 in the state probably.
Low 90s is a state rank.
Band 6s are slightly more common nowadays but yh 95 would be a state rank. Pretty sure they cap band 6s bc I don't know anyone who got 90+ but quite a few that got 89.
