But they will bring ur rank up as much as possible while remaining subtle to maximize your overall hsc and atar score to reflect well on the school.
This is, obviously, just all speculation but from what ive seen so far this seems to be the case

correct! To get a good reputation. Think people!!! Every secondary school teacher knows this!!!!!!!!!!!!!!!!!!!
