Preparing for the NSW Opportunity Class (OC) test? Build the mathematical reasoning and speed it rewards with free, weekly timed practice — the habit that matters more than any last-minute cram.
The OC test’s maths component rewards reasoning under time — here’s how KAOO builds it.
The OC maths section tests reasoning and problem-solving, not just computation. Regular varied problems build it.
Timed weekly papers train your child to work quickly without careless slips — exactly the test’s pressure.
Comfort with unfamiliar, worded, multi-step questions is what separates strong scores from good ones.
A short paper every week, months out, beats intensive last-minute cramming for both results and confidence.
When a topic trips your child up, step-by-step lessons rebuild it before the next challenge.
No tutoring fees — every weekly challenge and lesson on KAOO is free to use.
The Opportunity Class (OC) placement test is a NSW selective assessment for academically capable students, sat in Year 4 for entry into an OC class in Year 5. It assesses reading, mathematical reasoning and thinking skills. This page focuses on the maths reasoning component.
Expensive coaching isn’t the only path. The skills the OC maths section measures — reasoning, speed and resilience with unfamiliar problems — are built by consistent, timed practice over time. KAOO’s free Weekly Maths Challenge gives your child a fresh, marked paper every week, and the Mastery Maths lessons shore up any weak topic. Pair it with focused Year 4 maths practice.
Always confirm official test dates and registration windows with the NSW Department of Education; you can track key exam dates in the KAOO exam directory.
