Practical course certificate note
For practical, lab, and experiment courses, Eclat Institute may issue an internal Certificate of Completion/Attendance based on participation and internal assessment.
- This is an internal centre-issued certificate, not an MOE/SEAB qualification or accreditation.
- Recognition (if any) is determined by the receiving school, institution, or employer.
- For SEAB private candidates taking science practical papers, SEAB states you should either have taken the subject before or complete a practical course before the practical exam date.

What you must know
- Kinetic particle theory: solids (closely packed, vibrate), liquids (close but slide), gases (far apart, rapid and random). Energy changes drive melting/boiling/condensation/freezing.
- Diffusion: particles spread from high to low concentration; faster at higher temperature and for lighter molecules (e.g., H₂ vs CO₂).
- Atomic structure: protons (+1, mass 1), neutrons (0, mass 1), electrons (−1, mass ~1/1836); proton number = electrons in atom; nucleon number = p + n.
- Nuclide notation and isotopes:
