Questions parents ask

Does doing well in OC guarantee a selective high school place?

No. The Selective test is a separate test, sat in Year 6, and placement depends on that year’s results.

Are the sections the same?

Reading, Mathematical Reasoning and Thinking Skills appear in both, with different question counts and timing. Only the Selective test has a writing task.
