About the Grade 9 CBC Challenge
Grade 9 is the KJSEA year. This is practice, not a KJSEA paper or a result prediction: ten questions, each marked straight away with the working.

Getting the most out of it
Short and regular beats long and rare: one quiz a day across the three subjects, plus five minutes on the topics the score card suggests.
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.
