- How do organisms reproduce? — asexual modes; sexual reproduction in plants and humans; reproductive health.
- Heredity — variation, Mendel’s contribution, sex determination.
- Light — reflection and refraction — mirrors and lenses; formulas and magnification.
- Human eye and colourful world — accommodation; defects of vision; prism, atmospheric refraction, scattering.
- Electricity — Ohm’s law, series/parallel, heating effect, electric power.

Original practice prompts
Use these with the official syllabus above—these are study prompts, not a claimed board question paper.
- Choose one listed section and explain its main ideas aloud without looking at notes.
- Write five questions you would ask from that section, then answer them from memory.
- Mark one topic you find difficult and make a one-page revision sheet for it.
- After revising, attempt a past or sample paper only if its board, subject, language, and year match yours.
How to use this
- Read the syllabus or open the official paper from the source link.
- Use the related materials below to revise the same subject.
- Check an answer key or marking scheme only when it is published by the board.
