Internal assessment marks are awarded by your school through periodic tests, term tests, and practicals throughout the year. Focus your board exam preparation on the theory paper.

Internal Assessment (CCE Pattern)

  • • Conducted in June, July, October, November
  • • 20 marks each subject
Term Tests (2 per year)
  • • Conducted in September and February
  • • Comprehensive syllabus coverage
Practicals
  • • Science and Mathematics only
  • • Conducted by your school
  • • Marks included in internal assessment
⚠️ Eligibility Rule
You need minimum 25% in both periodic tests AND term tests to appear for the HSLC board exam. Don't ignore school tests - they are the gateway to your board exam.

What BOSEM Examiners Look For

📐Mathematics

Show every step - even if your final answer is wrong, correct working earns partial marks. Write 'Therefore' before final answers. Include units.

🔬Science

1–2 diagram questions per paper worth 3–5 marks. A labelled diagram with 4+ labels gets full marks. Practice: human eye, neuron, ray diagrams, circuits.

🗺️Social Science

Write in numbered points - never paragraphs. Each point = 1 mark. Always include dates in History answers. Examiner scans for key terms - bold them mentally as you write.

📖English

Format marks are separate from content marks. Losing the Subject line in a letter or the date in a notice = lost marks for nothing. Learn formats by heart.
