Effort & difficulty

INTENSITY

High

TYPICAL LOAD

4–5 hrs/wk

Concept-first and maths-rich. Once an idea clicks, problems fall into place.

Where students struggle

Translating word problems into the right model and equation.

Who it suits

Tends to thrive

Students who like asking why does that happen? and reaching for maths.

May find it a grind

Students hoping to avoid mathematics in a science.

How it scales

Scaled mean (per unit)

3-YEAR STABILITY

Very stable

Scaled mean by year: 2023 30.9 +0.2 2024 31.1 −0.1 2025 31.0

This is the spread of scaled marks across everyone who took the subject — not how hard it is. A high mean usually means a strong cohort sat it. The figures are from UAC’s latest scaling report (2025), with the year-by-year trend above.

Where might my mark scale to?

Set the HSC mark you’re aiming for. We’ll show a band of where that tends to scale — never a single number, never a prediction.

Expected HSC mark 85 / 100

4070100

Your course mark, out of 100 — a 2-unit course.

A mark in the high 80s tends to scale to roughly

38–40 per unit / 50

Scaled marks are measured per unit, out of 50 — the standard UAC scale. There’s no exact conversion, so this is a zone, not a pinpoint.

There’s no exact HSC-to-scaled conversion. Scaling depends on how the whole cohort performs each year, so treat this as a feel for the range — not a calculator.

Common questions

How does HSC Physics scale?

In the UAC Preliminary Report on the Scaling of the 2025 NSW HSC, Physics had a scaled mean of 31.0 out of 50 per unit, and its scaled mean has been very stable over recent years. Scaling reflects how academically strong the cohort is — not how hard the subject is — and there is no exact HSC-to-scaled conversion, so it's best read as a range, never a single number.

How hard is HSC Physics, and how much work is it?

Physics is high effort — typically 4–5 hrs/wk. Concept-first and maths-rich. Once an idea clicks, problems fall into place. Where students most often struggle: Translating word problems into the right model and equation.

What does HSC Physics build?

Physics uses maths to explain how the world works and builds real problem-solving skill. It especially develops numeracy & modelling, analytical reasoning, and practical & lab craft.

Who should take HSC Physics?

Students who like asking why does that happen? and reaching for maths. It may be more of a grind for students hoping to avoid mathematics in a science.

Where’s this data from?

Scaling figures are from the UAC Preliminary Report on the Scaling of the 2025 NSW HSC (Tables A1, A3). Scaled marks are out of 50 per unit.

There is no exact HSC-to-scaled conversion — for any one HSC mark there is a range of scaled marks, which is why we only ever show a band.
