• Description:

  The MS Word document comprises Form 3 Biology Paper 3 End Term 3 2026 Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  This practical paper evaluates practical laboratory competencies including biochemical food assays, macroscopic taxonomy, plant organ morphology, and experimental tissue osmosis. It is ideal for end-of-year school-based national assessment preparation towards the end of the term, and can also be effectively administered as a mid-term assessment for schools that have completed the syllabus early at the beginning of the term.

  • Duration: 1¾ Hours
