The Cambridge IGCSE Chemistry 0620 syllabus is designed for students aged 14–16 and is recognized globally for its academic rigor and preparation for further study.

Key aims include developing scientific knowledge, experimental skills, problem-solving abilities, and an understanding of the impact of science on society and the environment.

The syllabus encourages learners to be confident, responsible, reflective, innovative, and engaged in scientific inquiry.

Assessment is divided into Core and Extended levels, with multiple-choice, theory, and practical components:

• Core: Papers 1 (Multiple Choice) and 3 (Theory)

• Extended: Papers 2 (Multiple Choice) and 4 (Theory)

• Practical: Paper 5 (Practical Test) or Paper 6 (Alternative to Practical)

Assessment objectives and their weightings:

• Knowledge with understanding: 50%

• Handling information and problem-solving: 30%

• Experimental skills and investigations: 20%

Core subject content areas:

• States of matter

• Atoms, elements, and compounds

• Stoichiometry

• Electrochemistry

• Chemical energetics

• Chemical reactions

• Acids, bases, and salts

• The Periodic Table

• Metals

• Chemistry of the environment

• Organic chemistry

• Experimental techniques and chemical analysis

Key concepts introduced early in the syllabus:

• States of matter: solids, liquids, gases, and changes of state

• Atomic structure: protons, neutrons, electrons, electron shells, and the Periodic Table

• Isotopes: atoms of the same element with different numbers of neutrons

• Ionic and covalent bonding: formation, properties, and examples

• Giant covalent structures: graphite and diamond

Mathematical skills required include calculations involving relative atomic mass, empirical and molecular formulae, and interpreting data from experiments.

Sample equation in MathML for calculating relative atomic mass: Ar=∑i×a∑a where i is the isotope mass and a is the abundance.

Practical skills are emphasized, including safe laboratory techniques, data analysis, and drawing conclusions from experimental results.

The syllabus supports progression to advanced chemistry courses and is accepted by universities and employers worldwide.
