The Cambridge IGCSE Chemistry 0620 syllabus provides a comprehensive foundation in chemistry for students aged 14-16, 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 covers essential topics:

• 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 both including multiple-choice and theory papers, as well as practical or alternative-to-practical assessments.

Core assessment:

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

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

Extended assessment:

• 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 emphasizes transferable skills such as data analysis, problem-solving, scientific investigation, and safe laboratory practice.

Students are encouraged to develop curiosity, responsibility, reflection, innovation, and engagement with scientific principles and their real-world applications.

The course is internationally recognized and valued by universities and employers, providing a solid foundation for further education in chemistry and related fields.

Key equations and concepts such as stoichiometry, chemical reactions, and energetics are integral to the curriculum. For example, the general equation for a chemical reaction is: Reactants→Products

Stoichiometry calculations often use the mole concept: n=mM where n is the number of moles, m is mass, and M is molar mass.

Assessment objectives include knowledge recall, application of concepts, analysis of data, and evaluation of scientific information.
