Summary

• Description:

  The MS Word document comprises Form 3 Chemistry Paper 2 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 structured paper provides extensive assessment across periodic table periodicity, industrial gas extractions, chemical equilibria, gas stoichiometry, and halogen chemistry. 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: 2 Hours
  • Total Marks: 77 Marks
  • Number of Questions: 6 Questions (1 – 6)
  • Structure: 6 Compulsory Structured Questions (77 Marks)

  It covers the following topics:
