Physics HSC Scaling 2026 (NSW)
Under UAC’s 2025 HSC scaling, Physics had an average scaled mark of about 31 per unit (out of 50), scaling higher than 72% of NSW HSC courses. At the median, students had an HSC mark of 37.5 per unit and a scaled mark of 32.2. Scaled marks — not raw HSC marks — are what UAC adds up to build your ATAR.
Physics scaling table (2025 UAC)
HSC and scaled marks at each percentile, per unit (out of 50). A 2-unit course contributes twice these marks to your 10-unit aggregate.
| Percentile | HSC mark /50 | Scaled mark /50 |
|---|---|---|
| Top 1% (99th) | 47.5 | 47.2 |
| Top 10% (90th) | 45.5 | 43 |
| Top 25% (75th) | 42 | 38.8 |
| Median (50th) | 37.5 | 32.2 |
| Bottom 25% (25th) | 32 | 24 |
What this means for your ATAR
Your ATAR is built from your best 10 units of scaled marks — your best 2 units of English plus your best 8 units. Physics scales well: its average scaled mark of 31 is higher than 72% of NSW HSC courses, so it tends to pull your aggregate up relative to lower-scaling courses.

Figures are per unit (out of 50) from the UAC Report on the Scaling of the 2025 NSW HSC (Table A3). UAC publishes these as percentile statistics, not a mark-to-scaled conversion table — for any HSC mark there is a range of scaled marks. Re-stamped when UAC releases the new report each year.
