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, safe laboratory practices, and the ability to apply scientific methods to solve problems.

The syllabus encourages students to be confident, responsible, reflective, innovative, and engaged learners.

Assessment is divided into Core and Extended levels, with both including multiple-choice, theory, and practical components. Core is for grades C–G, Extended for grades A*–G.

Assessment objectives are:

• Knowledge with understanding (50%)

• Handling information and problem-solving (30%)

• Experimental skills and investigations (20%)

Main 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 covered include:

• Properties and changes of solids, liquids, and gases

• Atomic structure, isotopes, and the Periodic Table

• Ionic and covalent bonding, including properties of compounds

• Giant covalent structures and their uses

Students are expected to:

• Recall and explain scientific facts, laws, and theories

• Interpret and present information in various forms (symbolic, graphical, numerical)

• Plan and carry out experiments, analyze data, and evaluate methods

Mathematical skills are required for calculations such as relative atomic mass: Relative atomic mass=∑(isotope mass × abundance)Total abundance

The syllabus supports progression to Cambridge International AS & A Level Chemistry and is accepted by universities and employers worldwide.

Support resources include past papers, mark schemes, examiner reports, and online forums for teachers and students.
