Each go draws ten questions at random from the Grade 8 bank, so going again gives a different mix. Aligned to the KICD curriculum designs and checked by the CBC Guides team. Spot an error? Tell us.
Getting the most out of it
Ask your child to explain one worked answer back to you in their own words. If they can teach it, they know it.
Score card, levels and privacy
The level on the score card (Exceeding, Meeting, Approaching or Below Expectation) is indicative, worked out from the KJSEA mark ranges reported in the press. Ten questions cannot replace classroom assessment. How CBC grading works explains the levels.
There is no leaderboard. Comparisons are optional and only switch on once at least 20 real children have taken the same quiz. A parent joins with a nickname, a county and their consent. We never ask for surnames, schools or phone numbers.
