Your result appears here
All OC schools sorted by estimated band, which are within reach and, for your goal school, what it would take to get there.
How the OC Test is scored
The Opportunity Class Placement Test has three equally weighted parts: Reading, Mathematical Reasoning and Thinking Skills. There is no Writing test. The calculator turns each mark into a percentage and averages them, then compares that score with an estimated band for each OC school.
Re-run it after every mock. Watching schools move from Stretch to Within reach is the clearest sign the plan is working.
Questions parents ask
Is this the official score?
No. It is an estimate from practice marks. Real placement uses scaled scores set by the NSW Department of Education, and the marks needed change each year with demand.
Which marks should I enter?
Enter the marks from one recent full practice test, as printed: Reading out of 33, Mathematical Reasoning out of 35 and Thinking Skills out of 30. The OC test has no Writing section. A test sat under timed conditions gives the most useful estimate.
How is “What would it take?” worked out?
It adds the marks needed to reach the school’s estimated band to the weakest sections first, never past 95% in any one section, and rounds up to whole marks. It is one way to get there, not the only one. The time needed uses the steady weekly improvement iClass study plans are built around.
Do you keep my child’s results?
No. There is no sign-up and the marks are never saved. We only log that a check ran (the exam, any school you picked and your network address, to stop abuse) and delete that after 90 days.
