About IGCSE Chemistry 0620 and 0971 Syllabus
The Cambridge IGCSE Chemistry 0620 and IGCSE Chemistry 0971 syllabus introduces students to the principles of chemistry, with an emphasis on developing a solid understanding of theoretical concepts and practical skills. It’s designed for learners aged 14–16 and prepares them for further studies in chemistry or related fields such as medicine, engineering, and environmental science.
The syllabus is divided into key content areas:
- The Particulate Nature of Matter – atoms, molecules, and states of matter
- Experimental Techniques – methods of purification and separation
- Atoms, Elements, and Compounds – atomic structure, bonding, and the Periodic Table
- Stoichiometry – chemical formulae, equations, and reacting masses
- Electricity and Chemistry – electrolysis and ionic movement
- Chemical Energetics – exothermic and endothermic reactions
- Chemical Reactions – rates of reaction, acids, bases, and salts
- The Periodic Table – trends and properties of groups
- Metals – properties, reactivity, and extraction
- Air and Water – pollution, water treatment, and atmosphere
- Organic Chemistry – hydrocarbons, alcohols, and polymers
Students may choose either the Core (grades C–G) or Extended (grades A*–C) curriculum.
Assessment is through:
- Paper 1 – Multiple Choice (Core)
- Paper 2 – Multiple Choice (Extended)
- Paper 3 – Structured Questions (Core)
- Paper 4 – Structured Questions (Extended)
- Paper 5 – Practical Test
- Paper 6 – Alternative to Practical
