About KJSEA

KJSEA Integrated Science

Integrated Science brings biology, chemistry and physics together into a single Junior School learning area. Assessed in KJSEA under paper code 905, it is examined through both a theory paper and a practical.

The CBC approach emphasises scientific inquiry (observing, investigating, and drawing evidence-based conclusions) rather than recall alone. A theory paper and a practical are complemented by school-based assessment built up across Junior School.

How It Is Graded

Performance is reported against the four KJSEA bands: Exceeding, Meeting, Approaching and Below Expectations. The theory paper and practical together form the summative score, which combines with school-based assessment towards Senior School placement.

Revision Tips

Practise the practicals: setting up simple experiments, taking careful measurements, and recording observations in a clear format.

Learn key terms and definitions precisely, and be ready to explain the "why" behind a result, since inquiry and reasoning are central to the CBC.

Use practice questions across every strand to find weak spots early and build confidence before the assessment.
