WACE Mathematics Specialist hardest topics
Across 17,474 marked attempts on AusGrader, WACE Mathematics Specialist students average 59.2% on questions taken from board external papers. The lowest average of any command verb is evaluate on 37.7%, and the verb that costs the most marks is determine, which carries 37.0% of the paper against 4.4% for evaluate. These are self-selected users practising when they chose to, not the SCSA cohort under exam conditions.
How to read these numbers
- The figures are AusGrader users' marked attempts, not SCSA results. They corroborate what the board publishes about this subject and do not stand in for it.
- Any cut with fewer than 50 attempts is withheld, which on this page is 12 papers, 11 dot points and 14 verbs. Every figure shown carries its attempt count.
- Scores cover questions mapped to the WACE Mathematics Specialist syllabus from any board's external papers, which is why the sample is larger than the 12 SCSA papers alone. The paper table below is the exception and uses SCSA papers only.
- Internal assessment and school-uploaded exams are excluded throughout, so these averages differ from the ones on WACE Mathematics Specialist performance stats, which count every attempt.
Score by question type
| Question type | Average | Attempts |
|---|---|---|
| Short answer | 57.8% | 1,224 |
| Multiple choice | 59.5% | 16,250 |
Score by unit
| Unit | Average | Attempts |
|---|---|---|
| Unit 3: Complex Numbers, Functions, and 3D Vectors | 59.2% | 11,984 |
| Unit 4: Advanced Integration, Differential Equations, and Statistical Inference | 59.4% | 6,732 |
An attempt counts once per unit, so a question assessed across two units appears in both rows and the column adds to slightly more than 17,474.
The priority list: heavy topics with low scores
| Topic | Share of marks | Average | Attempts | Marks at risk |
|---|---|---|---|---|
| Vectors in three dimensions | 19.7% | 60.0% | 6,838 | 7.9 |
| Complex numbers | 18.4% | 57.5% | 3,057 | 7.8 |
| Rates of change and differential equations | 18.9% | 58.8% | 4,763 | 7.8 |
| Integration and applications of integration | 17.1% | 61.9% | 1,478 | 6.5 |
| Statistical inference | 12.6% | 56.0% | 537 | 5.5 |
| Functions and sketching graphs | 13.3% | 59.4% | 2,092 | 5.4 |
The topic list is close: 7.9 against 7.8 marks at risk separates first from second, so topic choice alone will not order revision. The dot-point list below spreads further.

Which command verbs cost the most marks
| Verb | Share of marks | Average | Attempts | Marks at risk |
|---|---|---|---|---|
| determine | 37.0% | 57.0% | 538 | 15.9 |
| evaluate | 4.4% | 37.7% | 52 | 2.7 |
| state | 7.8% | 68.4% | 50 | 2.5 |
| show | 7.6% | 73.1% | 73 | 2.0 |
| express | 1.5% | 57.1% | 58 | 0.6 |
Evaluate has the lowest average on the page at 37.7%, and it is not where the marks go. Determine averages 57.0% but carries 37.0% of the paper against 4.4%, so it puts 15.9 marks per 100 at risk against 2.7. Each verb above is practised in the WACE Mathematics Specialist question bank, where the marking criteria show what SCSA expects the answer to do.

Frequently asked questions
Which WACE Mathematics Specialist dot points give the best return on revision time?
4.2.7 (2.6 marks at risk per 100), 4.3.5 (2.0 marks at risk per 100) and 4.2.1 (2.0 marks at risk per 100). Marks at risk combines a dot point's share of paper marks with the marks students drop on it, so it ranks by recoverable marks and not by score alone.
How many attempts is each WACE Mathematics Specialist figure based on?
17,474 marked attempts overall, with the per-row count shown in every table. Any cut below 50 attempts is withheld instead of published.
Do these averages show how the SCSA cohort performed?
No. They are AusGrader users' marked attempts, a self-selected group practising when they chose to and often without exam timing. They corroborate what SCSA publishes about this subject and do not replace it.
