they dont actually say what the highest mark is anywhere.. so you have to go on if people know someone in the top 20 list and what they got. unfortunately my connections to such people are limited to earth and environmental science, mathematics, legal studies and a number of languages so i cant really help there
hopefully someone has a connection.
i think aligning relates to your actual hsc mark, like where you lie in comparison to other, and scaling is more of a uai working out thing (dont quote me on that though)
[edit] hahaha i got pwned by laz
where do they release the highest mark?
