damn i have a mate who is 2026 and their cohort is crazy at math, penrith math program (in junior years at least) is imo really good and they do a bunch of topics early, i heard i becomes shit in senior though and all other subjects are average
penrith kids are better socially i swear girra kids are fucking weird, experience from tutoring, but Penrith sucks ass cause you cant do the subjects you wanna do and have to deal with a shit load of requirements
percentage of students who received band 6, lets say a school has a 400 students and 40 get band 6 they would be ranked lower then a school with 100 students and 30 band 6
