| They don't reflect anything to do with your UAI.
The UAI is all about ranking students for entrance to university, but only 30% of HSC students actually proceed to tertiary study. The UAI is pretty much irrelevant to the other 70% of students.
HSC marks report performance in terms of set standards (described by the performance bands) and indicate what a typical student at that level knows and can do.
