OC and Selective Exam Study Guide for NSW Primary Students

Why a steady routine works best

Preparing for the Opportunity Class (OC) test and the Selective School placement test works best when it follows a steady, well-organised routine. The OC test is taken by Year 4 students applying for Year 5 placement, while the Selective test is taken by Year 6 students applying for Year 7 entry, so families with children in Years 2-6 are often planning for one or both. This guide sets out a realistic weekly study plan that fits around regular school and family life.

Consistent short sessions build skills more reliably than occasional long ones, and a plan that includes practice tests, targeted skill work, and honest error review gives families a clear picture of progress at every stage.

Building the routine, step by step

1. Build a consistent weekly routine. Choose three or four regular study blocks of 30-45 minutes each, at times when your child is alert rather than tired from a long school day. A common pattern is short sessions on three weekday afternoons plus one longer weekend session. Display the schedule somewhere visible, keep the same days each week, and treat the sessions as a normal part of the week rather than something that can be easily skipped.
2. Mix practice tests with targeted skill practice. Practice tests familiarise students with the question styles used in mathematical reasoning, thinking skills, and reading, and they build stamina under timed conditions. Use one practice test about once a week, then look closely at the results to identify which skills need work. Between tests, spend sessions on targeted drills in those weaker areas, rather than doing test after test without changing anything.
3. Use explanations after every mistake. When your child answers incorrectly, read the explanation for that question together before moving on. Ask your child to explain the reasoning back to you in their own words, and keep a simple error log recording the topic and the type of mistake made. Reviewing explanations turns each error into a genuine learning moment, which is far more effective than simply checking the score at the end.
4. Track progress with analytics. Parents of NSW primary students can use a learning platform with built-in analytics, such as AIscholar, to see performance trends across topics, question types, and sessions. Review the charts together every two weeks, note which areas are improving, and shift practice toward the skills that remain weak. Regular review of the data keeps the study plan focused and shows the child that their effort is producing measurable gains.
5. Manage workload alongside regular school. Test preparation should never crowd out homework, sport, or sleep. If a particular week is busy with school assignments or sport, drop one study session rather than letting either homework or preparation suffer. Speak with your child's class teacher about the schedule, and use school holidays for longer practice sessions while keeping term time lighter and steadier.

Example question

Answer and reasoning

The correct option is B) 15. One-quarter of 24 is 6, so Lucy gives away 6 marbles and is left with 18. She then loses 3 marbles, which leaves her with 15. Option A is the number she has immediately after giving the marbles away, but it ignores the 3 that are lost. Option C only subtracts the 3 lost marbles and ignores the quarter given to the brother. Option D does not follow from either step in the problem.
