HSC Mathematics Extension 1 scaling

Review Year 12 scaling benchmarks for Mathematics Extension 1, where a cohort of 9,279 recorded a scaled mean of 39.7 out of 50.

Year 11 marks are not scaled. The 2025 Year 12 scaled profile is provided as historical context only.

39.7 Scaled mean out of 50

41.5 Scaled median 2025 cohort

44.9 Upper quartile 2025 cohort

UAC calculates scaling from unreleased raw exam and assessment marks, meaning NESA-reported HSC marks cannot be uniquely converted into scaled marks. Estimate your overall ATAR using five years of historical scaling data from UAC.
