Opportunity classes (OC) are like Selective Primary Schools for students in Years 5 and 6. Students in NSW sit for the Opportunity Class test in Year 4. The OC test covers similar topics to those the Selective School Tests cover (English, Maths and General Ability) in two sections about 30 minutes apart but has no Written Expression. In many areas it is much harder to make it into an OC school than it is to make it into even an average Selective High School. There are 75 OC schools in NSW including 36 in Sydney. Practice is the key to excel in the tests. You can take the tests on our website for practice.
