HSC Maths Standard vs Advanced (2026 decision guide)
Mathematics Advanced had a higher scaled mean than Standard 2 in 2025 (31.9 vs 23.3 per unit, UAC), but your own scaled mark depends on where you finish in the course: a 90th-percentile Standard 2 student (37.3) out-scaled a median Advanced student (33.2). Choose Advanced if your target degrees assume it and you can finish in the upper half; otherwise Standard 2 is a sound ATAR choice.
Jump to a section
Standard 2 or Advanced is one of the most common Year 10 subject questions in NSW. The answer depends on three things: what your likely university courses expect, where you would finish in each course, and how much time you can give maths.
What each course covers
These are the 2017 syllabuses, examined in the 2026 HSC.
Mathematics Standard 2
- Algebra and modelling (linear and non-linear relationships)
- Measurement, including right-angled and non-right-angled trigonometry, rates and ratios
- Financial mathematics: investments, loans and annuities
- Statistical analysis, including bivariate data and the normal distribution
- Networks, including network flow and critical path analysis
The HSC exam is 2.5 hours plus reading time.
Mathematics Advanced
- Functions, including exponential and logarithmic functions
- Trigonometric functions and their graphs
- Calculus: differentiation, integration and their applications
- Financial mathematics through sequences and series
- Statistical analysis, including discrete and continuous random variables and the normal distribution
The HSC exam is 3 hours plus reading time. Advanced is also the course you must take to do Mathematics Extension 1.
Scaling: what UAC's 2025 data shows
All figures are scaled marks per unit, out of 50, from Table A3 of UAC's scaling report on the 2025 HSC.
| Group (2025) | Students | Scaled mean | 25th percentile | Median | 75th percentile | 90th percentile |
|---|---|---|---|---|---|---|
| Mathematics Advanced (all) | 16,809 | 31.9 | 25.9 | 33.2 | 38.9 | 42.9 |
| Mathematics Advanced (without Extension 1) | 11,521 | 29.4 | 23.3 | 30.4 | 36.3 | 40.9 |
| Mathematics Standard 2 | 31,762 | 23.3 | 15.1 | 23.2 | 31.5 | 37.3 |
What this means:
- The average Advanced student scales higher than the average Standard 2 student because Advanced attracts students who do well across all their subjects.
- If you would take Advanced without Extension 1, compare yourself with the 29.4 group, not the headline 31.9.
- Position matters. A Standard 2 student at the 75th percentile (31.5) was close to a median Advanced-only student (30.4). A 90th-percentile Standard 2 student (37.3) was above a 75th-percentile Advanced-only student (36.3).
UAC warns that raw and HSC marks can't be converted to scaled marks with a simple table, so be wary of any "80 raw = X scaled" claims.
For scale: in 2025 an aggregate (best 10 units, out of 500) of 400 corresponded to an ATAR of 94.40, 350 to 86.45 and 300 to 77.40. Two units of maths is one-fifth of that aggregate.
University requirements
Most NSW universities list assumed knowledge (content lecturers assume you know) and some list prerequisites (subjects you must have). Degrees in engineering, science, computing, economics, commerce and similar quantitative fields commonly assume Mathematics Advanced, and some assume Extension 1.
- Check each course in the UAC course search and on the university's own page for the year you will start.
- If you enter without the assumed knowledge, universities usually recommend or require a bridging course.
Deciding
- Check what your likely degrees assume or require. This comes first.
- Estimate where you would finish. Your Year 10 results and your teacher's view are the best guide. Under the Mathematics K-10 Syllabus (2022), Stage 5 uses a Core-Paths structure instead of the old 5.1/5.2/5.3 pathways. The Core outcomes provide the foundation for Standard 2; ask your teacher how much Path content you have covered and how you went, because Advanced builds directly on it.
- Be honest about time. Advanced needs steady practice across both years.
- Consider Extension 1 only if you are comfortably in the upper part of your Advanced class. It scaled to a mean of 39.7 in 2025, but only helps if you can keep up.
Choosing Advanced purely "for the scaling". If you would finish in the bottom quarter of Advanced (25.9 or less in 2025), a strong Standard 2 result is likely to scale higher, and you keep more time for your other subjects.
Choosing Standard 2 without checking assumed knowledge. If your target degree assumes Advanced, you may need a bridging course before or during first year.
If you are starting Year 11 in 2026
You are on the new Mathematics Standard and Mathematics Advanced 11-12 syllabuses (2024). They started with Year 11 in Term 1 2026, start Year 12 in Term 4 2026, and are first examined in the 2027 HSC. Changes include updated school-based assessment requirements, a single "working mathematically" outcome, technology embedded in the content, and removal of common content between Standard and Advanced in the HSC exam.
Students sitting the HSC in 2026 stay on the 2017 syllabuses.
