The Cambridge IGCSE Chemistry 0620 syllabus provides a comprehensive foundation in chemistry for students aged 14 to 16, preparing them for further study and practical application.

Key aims include developing scientific knowledge, understanding experimental skills, using scientific data, and communicating effectively using scientific terminology and conventions.

The syllabus emphasizes transferable skills such as independent thinking, problem-solving, analysis, and safe laboratory practice.

Major topics covered are:

• 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

Assessment is divided into Core and Extended levels, with multiple-choice and theory papers, as well as practical or alternative-to-practical tests.

Core assessment includes:

• Paper 1: Multiple Choice (Core) – 40 marks, 30%

• Paper 3: Theory (Core) – 80 marks, 50%

Extended assessment includes:

• Paper 2: Multiple Choice (Extended) – 40 marks, 30%

• Paper 4: Theory (Extended) – 80 marks, 50%

Practical assessment options:

• Paper 5: Practical Test – 40 marks, 20%

• Paper 6: Alternative to Practical – 40 marks, 20%

The syllabus encourages students to appreciate the impact of chemistry on society and the environment, and to develop a lifelong interest in science.

Mathematical skills, data analysis, and understanding of scientific conventions (signs, symbols, terminology, and nomenclature) are integral to the course.

Equations and calculations are essential, including:

• n=mM (amount of substance in moles, where n = moles, m = mass, M = molar mass)

• c=nV (concentration, where c = concentration, n = moles, V = volume)

The course is internationally recognized and valued by universities and employers, supporting progression to advanced chemistry studies.
