Sample questions at this year level and subject
These are Year 5 Reading questions from Skillo's general practice bank — not written specifically for the NSW OC test. They're a useful proxy for Reading practice at this level while our OC-specific question bank grows.
SAMPLE QUESTION 1 — Medium
Read the passage below, then answer the question. Australia has strict biosecurity laws to protect its unique wildlife and agricultural industries from introduced pests and diseases. Travellers arriving in Australia must declare any food, plants, or animal products they are carrying. Items that could carry insects, seeds, or bacteria may be confiscated at the border. The cane toad is a well-known example of the damage introduced species can cause — it was brought to Australia in 1935 to control beetles on sugar cane farms but instead spread rapidly, harming native wildlife. This history explains why Australia takes biosecurity so seriously. What lesson does the passage suggest Australians have learned from the cane toad?

How to prepare
OC preparation works best as steady, low-pressure reading and reasoning practice over several months rather than last-minute cramming — the test rewards comprehension stamina more than memorised facts.
Skillo's sample questions here are drawn from our general Year 4/5 Reading bank rather than OC-specific material — use them alongside official NSW Department of Education resources for the fullest picture of the real test.

Who can sit OC?
Year 4 students at a NSW government school, or applying to attend one, who are Australian citizens or permanent residents. Successful students enter the OC program in Year 5.
How many OC places are available?
About 1,840 OC places are offered each year across 77 NSW schools, plus Aurora College for rural and remote students. Around 12,000 to 13,000 students apply annually, so success rates are roughly 15% statewide.
What is a competitive score?
NSW DET does not publish numerical cut-off scores. Students receive performance band placements per section (e.g. top 10%, next 15%, next 25%, lowest 50%). Competitive metropolitan OC schools typically admit students placing in the top 10 to 20% of applicants.
Is this an official NSW OC practice test?
No — Skillo is an independent, free practice resource. These sample questions and worked solutions are authored by Skillo, not by the NSW Department of Education or Cambridge Assessment, and are not official OC test material.
