OC Practice Tests and Past Papers
Updated:
Reading time: 4 to 5 minutes
Where to find the official practice tests, what they can and cannot tell you, and how to practise once your child has worked through them.
TL;DR
- The Department publishes official practice tests, free. These are papers from past years.
- There are only a handful. Once your child has seen a paper, it is spent.
- They give a result, not a diagnosis. They will not tell you which skills to work on next.
- The test has three equally weighted parts: Reading, Mathematical Reasoning and Thinking Skills.
Start with the official practice tests
The NSW Department of Education publishes official practice tests, free to everyone. These are papers from past years, which makes them the most reliable place to start.
NSW Department of Education: Opportunity class practice tests
Sit one under realistic conditions before you do anything else. Quiet room, no help, and timed. A first attempt done properly tells you far more than several done casually.
Are there OC past papers?
Yes. The official practice tests linked above are papers from past years, currently 2021, 2022 and 2023, and they are free to download.
There are only a few, so use them deliberately rather than working through all of them in a fortnight. Sit one early to get a baseline and keep one back for closer to the test.
What the official tests do and don't tell you
They are good at one thing: showing your child what the test looks like. The phrasing, the pacing, the way questions are framed. That familiarity is worth having, and it removes a surprise on the day.
There are two things they cannot do.
They run out. There is a fixed number of official questions. Once your child has worked through them, sitting the same paper again measures memory rather than skill. The score goes up and tells you nothing.
They give a result, not a diagnosis. A mark out of a section tells you how it went. It does not tell you whether the problem was the concept, the reading of the question, or simply running out of time. Those need different responses, and the paper cannot distinguish between them.
What to practise
The test has three components, each weighted equally, so a weakness in one carries the same cost as a weakness in another.
- Reading: comprehension, inference, vocabulary and how a text is put together.
- Mathematical Reasoning: applying number, space and measurement to unfamiliar problems.
- Thinking Skills: deduction, evaluating arguments and spotting flawed reasoning.
If you want the question styles broken down in detail, the OC question types guide walks through each one.
How to practise so it counts
More practice tests is not the same as better preparation. Sitting test after test shows you the same weaknesses repeatedly without fixing any of them.
What changes a score is the loop after the test: work out which specific skill caused each mistake, learn that skill, drill it until it is automatic, then re-test to check it held. A wrong answer is only useful if it leads somewhere.
Two practical habits matter more than volume. Review every mistake properly, reading why the right answer is right rather than just noting the correct letter. And spread practice out rather than cramming it, because spacing is what moves a skill into long-term memory.
For how much to do and when, see the OC study plans and the weekly practice rhythm.
When you run out of official papers
This is where most families get stuck. The official tests are done, the child has seen every question, and there is no obvious way to tell what to work on next.
That is the gap OC Test Prep is built for. Thousands of questions with an explanation for every one, so a mistake becomes a lesson rather than a mark. Timed tests that mirror the real format. And a weekly plan that names the few things worth working on this week, based on what your child actually got wrong, then re-tests to show whether it worked.
