    1B Human Biology – the skeletal/muscular system, the senses and human reproduction
    1C Animals, plants and micro-organisms

    2A Classification of substances
    2B Air, oxygen, carbon dioxide and water
    2C Atomic structure, reactions and compounds
  3. Physics

    3C Magnetism, electricity and electronics
Both Ordinary level and Higher level students must study all three sections.
There are two assessment components: coursework (35% of the marks) and an examination paper (65% of the marks). The coursework is common to both Ordinary level and Higher level. There are separate examination papers for each level.
