How the HSC ATAR works
Your ATAR comes from your scaled marks in 10 units - your best 2 units of English (always included) plus your best 8 remaining units - giving an aggregate out of 500 that UAC converts to a rank. HSC marks in each course are scaled to what they would be if all students had taken the course.
Scaling source: UAC Report on the Scaling of the 2025 NSW HSC (Table A3). Rules and dates are reviewed separately on each linked guide.
