Summary

• Description:

  The PDF document comprises Nyahokakira Cluster II Physics Paper 3 2026 Mock Exam with Marking Scheme. The marking scheme is in a different document.

  It was a KCSE Physics Paper 3 (232/3) Practical examination.

  This laboratory exam assesses students' practical competencies in electrical circuit assembly, graphical slope analysis, density measurements, and optical refraction using glass blocks. A crucial practical revision paper available for PDF download to help candidates cross-examine laboratory findings and scoring rubrics in the marking scheme.

  • Month Administered: July 2026
  • Duration: 2 hours 30 minutes
  • Total Marks: 40 marks
  • Number of Questions: 2 questions (Questions 1 and 2)
  • Structure: Two compulsory practical questions carrying 20 marks each: Question 1 covers current electricity and internal resistance; Question 2 covers mechanics, volume, density, and optical critical angle determination.
