Summary

• Description:

  The MS Word document comprises KCSE 2026 Biology Paper 2 Prediction Paper with Answers (Set 3). The PDF version is also available upon your request. The marking scheme is in a different document.

  It was a KCSE Biology Paper 2 prediction examination designed to prepare candidates for the national assessment.

  This paper assesses advanced biological comprehension, data interpretation, physiological adaptations, and essay-based synthesis through structured problem sets and graphical analysis.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 8 (Questions 1 - 8)
  • Structure: Two sections; Section A (40 marks, compulsory structured questions 1 - 5) and Section B (40 marks, compulsory data question 6, and a choice between essay question 7 or 8)
