QCE Psychology hardest topics
Across 25,110 marked attempts on AusGrader, QCE Psychology students average 63.1% on questions taken from board external papers. The lowest average of any command verb is compare on 41.4%, and the verb that costs the most marks is describe, which carries 28.1% of the paper against 2.9% for compare. These are self-selected users practising when they chose to, not the QCAA cohort under exam conditions.
How to read these numbers
- The figures are AusGrader users' marked attempts, not QCAA 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 19 dot points, 1 question type and 14 verbs. Every figure shown carries its attempt count.
- Scores cover questions mapped to the QCE Psychology syllabus from any board's external papers, which is why the sample is larger than the 12 QCAA papers alone. The paper table below is the exception and uses QCAA papers only.
- Internal assessment and school-uploaded exams are excluded throughout, so these averages differ from the ones on QCE Psychology performance stats, which count every attempt.
Score by past paper
| Year | Paper | Average | Attempts |

| 2025 | Paper 2 | 63.8% | 520 |
| 2024 | Paper 1 | 70.5% | 648 |
| 2024 | Paper 2 | 60.9% | 253 |
| 2023 | Paper 1 | 69.9% | 565 |
| 2023 | Paper 2 | 63.0% | 126 |
| 2022 | Paper 1 | 60.3% | 550 |
| 2022 | Paper 2 | 61.2% | 126 |
| 2021 | Paper 1 | 64.2% | 396 |

| 2020 | Paper 1 | 69.5% | 505 |
| 2020 | Paper 2 | 39.4% | 53 |
The lowest average belongs to the 2020 Paper 2 on 39.4% from 53 attempts, and the highest to the 2024 Paper 1 on 70.5% from 648 attempts. A paper's average reflects both how hard it was and who chose to sit it, so treat the spread as a guide to which papers make demanding practice.
Score by question type
| Question type | Average | Attempts |
|---|---|---|
| Multiple choice | 63.2% | 22,391 |
| Short answer | 63.5% | 2,714 |
Score by unit
| Unit | Average | Attempts |
|---|---|---|
| Unit 3: Individual thinking | 62.7% | 21,419 |
| Unit 4: The influence of others | 67.2% | 2,171 |
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 25,110.
The priority list: heavy topics with low scores
| Topic | Share of marks | Average | Attempts | Marks at risk |
|---|---|---|---|---|
| Learning | 14.9% | 58.4% | 6,380 | 6.2 |
| Memory | 17.8% | 65.6% | 8,123 | 6.1 |
| Brain function | 13.9% | 63.2% | 8,837 | 5.1 |
| Interpersonal processes | 13.1% | 66.9% | 168 | 4.3 |
| Social psychology | 10.0% | 61.5% | 828 | 3.9 |
| Attitudes | 14.9% | 75.1% | 550 | 3.7 |
| Sensation and perception | 8.5% | 65.1% | 140 | 3.0 |
| Cross-cultural psychology | 6.9% | 69.1% | 657 | 2.1 |
The topic list is close: 6.2 against 6.1 marks at risk separates first from second, so topic choice alone will not order revision. The dot-point list below spreads further.
The same cut at dot-point level
| Dot point | Content | Share of marks | Average | Attempts | Marks at risk |

Which command verbs cost the most marks
| Verb | Share of marks | Average | Attempts | Marks at risk |
|---|---|---|---|---|
| describe | 28.1% | 63.0% | 845 | 10.4 |
| identify | 20.5% | 63.1% | 751 | 7.6 |
| explain | 14.5% | 59.4% | 317 | 5.9 |
| justify | 5.9% | 62.1% | 234 | 2.2 |
| draw | 3.4% | 47.6% | 81 | 1.8 |
| predict | 3.8% | 53.6% | 102 | 1.8 |
| compare | 2.9% | 41.4% | 72 | 1.7 |
| provide | 5.5% | 73.6% | 89 | 1.4 |
Compare has the lowest average on the page at 41.4%, and it is not where the marks go. Describe averages 63.0% but carries 28.1% of the paper against 2.9%, so it puts 10.4 marks per 100 at risk against 1.7. For the plain ranking of verbs by score, and what QCAA has said about each, read the QCE Psychology study guide.

Frequently asked questions
Which QCE Psychology past paper do students score lowest on?
The 2020 Paper 2, averaging 39.4% across 53 marked attempts on AusGrader. The 2024 Paper 1 is the highest on 70.5%.
Which QCE Psychology dot points give the best return on revision time?
3.4.2 (2.7 marks at risk per 100), 3.3.9 (2.2 marks at risk per 100) and 3.2.2 (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 QCE Psychology figure based on?
25,110 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 QCAA 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 QCAA publishes about this subject and do not replace it.
