How the Challenge Works

Handwritten. Photographed.
Marked by a trainer.

This is not a multiple-choice quiz. Every question requires you to work through a problem the way you would in an exam or on the job — on paper, showing full working. Trainers review your method, not just your final answer.

Questions are drawn directly from the Learning Outcomes and Content columns of the TVET CDACC RAC Level 6 curriculum. No question appears here that is not in the syllabus you are being assessed on.

01 Select a topic — each corresponds to a Learning Outcome in the curriculum
02 Read the question — note the curriculum reference at the top of each card
03 Work it out on paper — show every step of your method
04 Photograph your working — flat, well-lit, all steps visible
05 Submit via email — your answer goes directly to the KSBTS trainer
