Summary

• Description:

  The PDF document comprises KALA Joint Trials 2024 Physics Paper 2 Exam with Answers and Marking Scheme. The marking scheme is in a different document.

  It was a KCSE Physics Paper 2 (232/2) Joint Trial examination administered in August 2024.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 18
  • Paper Structure: Two Sections – Section A and Section B.

  The paper was structured as follows:

  • Section A (25 marks): Thirteen compulsory short-answer questions covering fundamental concepts in waves, electricity, electronics, and modern physics.
  • Section B (55 marks): Five structured questions requiring explanations, calculations, diagrams, and interpretation of physical phenomena.

  The examination assessed learners’ understanding of wave motion, electricity and magnetism, electronics, optics, and modern physics.
