INTENSITY
High
TYPICAL LOAD
4–5 hrs/wk

Blends programming theory with a substantial build project.

Where students struggle

Debugging the project and the more abstract theory topics.

Who it suits
Tends to thrive
Students who like coding, logic and building things that run.
May find it a grind
Students expecting to coast without actually building anything.

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
35–38 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.
0 10 20 30 40 50 mean 26.7
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 Software Engineering scale?

In the UAC Preliminary Report on the Scaling of the 2025 NSW HSC, Software Engineering had a scaled mean of 26.7 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 Software Engineering, and how much work is it?

Software Engineering is high effort — typically 4–5 hrs/wk. Blends programming theory with a substantial build project. Where students most often struggle: Debugging the project and the more abstract theory topics.

What does HSC Software Engineering build?

Software Engineering teaches you to design, code and build real software. It especially develops analytical reasoning, independent research, and numeracy & modelling.

Who should take HSC Software Engineering?

Students who like coding, logic and building things that run. It may be more of a grind for students expecting to coast without actually building anything.

Where’s this data from?

Scaling figures are from the UAC Preliminary Report on the Scaling of the 2025 NSW HSC (Tables A1, A3 (Software Engineering succeeds Software Design & Development)). 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.

The skills, effort and “who it suits” notes are Intuition Education’s editorial guidance, not UAC data.
