Summary

• Description:

  The MS Word document comprises Mmalina Joint Trial Physics Paper 1 2026 Mock Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  It was a KCSE Physics 232/1 examination.

  This paper examines fundamental principles of mechanics, properties of matter, thermal physics, fluid dynamics, and gas laws. Designed to sharpen problem-solving and quantitative reasoning, it prepares students thoroughly for KCSE Physics Paper 1 national examinations.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 18 (Questions 1 - 18)
  • Structure: Section A (25 marks, questions 1-13, compulsory short questions) and Section B (55 marks, questions 14-18, compulsory structured and calculation problems).
