Summary

• Description:

  The PDF document comprises Navakholo Term 1 Joint Evaluation Physics Paper 1 March 2026 Pre-Mock Exam with Marking Scheme. The marking scheme is in a different document.

  It was a KCSE Physics Paper 1 (Theory) examination. This paper assesses Form 4 candidates on mechanics, properties of matter, and thermal physics — testing both conceptual understanding and the ability to perform structured calculations under examination conditions.
