VCE Psychology hardest topics
Across 52,242 marked attempts on AusGrader, VCE Psychology students average 63.2% on questions taken from board external papers. The lowest average of any command verb is define on 44.8%, and the verb that costs the most marks is explain, which carries 18.5% of the paper against 0.0% for define. These are self-selected users practising when they chose to, not the VCAA cohort under exam conditions.
How to read these numbers
- The figures are AusGrader users' marked attempts, not VCAA 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 1 dot point, 1 question type and 31 verbs. Every figure shown carries its attempt count.
- Scores cover questions mapped to the VCE Psychology study design from any board's external papers, which is why the sample is larger than the 6 VCAA papers alone. The paper table below is the exception and uses VCAA papers only.
- Internal assessment and school-uploaded exams are excluded throughout, so these averages differ from the ones on VCE Psychology performance stats, which count every attempt.
Score by past paper
| Year | Exam | Average | Attempts |
|---|---|---|---|
| 2025 | Exam | 61.8% | 8,215 |
| 2024 | Exam | 63.9% | 7,910 |
| 2023 | Exam | 63.8% | 7,864 |
| 2022 | Exam | 60.0% | 7,201 |
| 2021 | Exam | 62.9% | 9,231 |
| 2020 | Exam | 65.9% | 10,475 |
The lowest average belongs to the 2022 Exam on 60.0% from 7,201 attempts, and the highest to the 2020 Exam on 65.9% from 10,475 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% | 50,854 |
| Short answer | 65.7% | 1,376 |
Score by unit
| Unit | Average | Attempts |
|---|---|---|
| Unit 4: How is mental wellbeing supported and maintained? | 62.5% | 29,195 |
| Unit 3: How does experience affect behaviour and mental processes? | 64.1% | 24,516 |
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 52,242.

Define has the lowest average on the page at 44.8%, and it is not where the marks go. Explain averages 58.1% but carries 18.5% of the paper against 0.0%, so it puts 7.8 marks per 100 at risk against 0.0. Each verb above is practised in the VCE Psychology question bank, where the marking criteria show what VCAA expects the answer to do.
What this does not measure
Where to practise
Work the priority list from the top: How is scientific inquiry used to investigate mental processes and psychological functioning? and How does the nervous system enable psychological functioning? first, then the dot points above. Each topic page holds real VCAA questions with marking criteria attached. For what the papers actually cover, read VCE Psychology most tested topics.
Frequently asked questions
Which VCE Psychology past paper do students score lowest on?
The 2022 Exam, averaging 60.0% across 7,201 marked attempts on AusGrader. The 2020 Exam is the highest on 65.9%.
Which VCE Psychology dot points give the best return on revision time?
4.3.1.2 (3.6 marks at risk per 100), 3.2.1.1 (3.2 marks at risk per 100) and 4.3.2.2 (1.9 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 VCE Psychology figure based on?
52,242 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 VCAA 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 VCAA publishes about this subject and do not replace it.
