The Grade 6 CBC Challenge is a free ten-question quiz in Mathematics, English and Science & Technology. It is designed for upper primary learners who are preparing for KPSEA or simply want to check their understanding at the end of a term. This guide shows parents how to turn a quick quiz into a focused revision plan without pressure.

What Grade 6 learners will see
Questions come from the Grade 6 curriculum strands. In Science & Technology the bank covers fungi, invertebrates, the human circulatory system, the composition of air and air pollution, change of state and the water cycle, light, and levers and slopes as simple machines. Mathematics covers whole numbers, fractions and decimals, measurement, money and simple geometry. English checks grammar, vocabulary and short comprehension passages.
Each attempt picks ten questions at random, gives instant feedback and lists the topics to revise. Learners can retake it as often as they like, and new questions appear on most attempts.
Before the first attempt
- Choose a quiet time, ideally after a meal and before the learner is tired.
- Have a pencil and rough paper ready. Grade 6 Mathematics questions are easier with working shown.
- Explain that the score is for planning, not for marks. Many children relax and do better once they hear this.
Turning results into a plan
When the round ends, write the “revise these” topics on a sheet of paper and stick it somewhere visible. Take them one at a time across the week. For a topic like the circulatory system, a ten-minute session might be: read the notes, draw and label the heart with arrows showing where blood goes, then explain to a parent which vessels carry blood away from the heart (arteries) and which bring it back (veins). For simple machines, look around the house: a pair of scissors, a bottle opener and a wheelbarrow are all levers, and a ramp at a shop entrance is a slope.
Practical examples like these help Grade 6 learners remember far better than re-reading.
Using Grade 6 revision papers next
Once a learner is scoring well on the Challenge, move to full papers. Our Grade 6 revision papers give longer questions in the KPSEA style. A good rhythm is one Challenge round on Monday to warm up, one paper section mid-week, and a retest on Friday. The KPSEA guide explains how the assessment works and what it is used for.
Typical Grade 6 slips
- Confusing evaporation (liquid to gas) with condensation (gas to liquid).
- Thinking a spider is an insect. Insects have six legs and three body parts; spiders have eight legs.
- Forgetting that mushrooms and yeast are fungi, not plants.
- In Mathematics, lining up decimals wrongly when adding or subtracting.
Keep it encouraging
Grade 6 is still primary school. Short sessions, lots of praise for effort and a visible record of improvement matter more than any single score. If your child gets the same question wrong twice, sit with them and go through the explanation together rather than repeating the quiz straight away.
The questions are written by the CBC Guides team and checked by a teacher. CBC Guides is an independent revision site, not KNEC or KICD.
