What parents and children are saying

Join hundreds of NSW students already preparing for the OC test with confidence

On the timed digital test, she froze up watching the countdown timer. After a few practice runs, she's learned to pace herself. I'm so glad we discovered this now!

— LH, parent

I can't believe I'm saying this but this was actually fun.

— RF, student

The parent report aligns with what I already knew about my child's progress — and it's great to see I'm focusing on the right areas. It also gave me new suggestions I hadn't thought of.

EXPERIENCE THE TEST FORMAT

See how practice questions work — with instant feedback and detailed explanations

Ms. Chen's class will be allowed to watch a movie on the last day of term. There are two classrooms available and two televisions, so the class can be split into two, and watch two different movies, if needed.

Ms. Chen does a survey of the class, asking them what they would like to watch. She notices that most of the girls in the class want to watch Harry Potter, and most of the boys want to watch Star Wars.

Ms. Chen: "There are the same number of boys and girls in the class. So I should put the girls in one classroom and show them Harry Potter, and put the boys in the other classroom to watch Star Wars." Which one of the following sentences shows the mistake Ms. Chen has made?

Harry Potter and Star Wars may be different lengths.

There may be some boys who would prefer Harry Potter, and some girls who would prefer Star Wars.

Some of the boys might only have chosen Star Wars because their friends did.

Different numbers of boys and girls might miss the last day of term.

We have thousands more questions like this — with detailed explanations for every one.
