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

Key aims include:

• Acquiring scientific knowledge and understanding of theories and practice.

• Developing experimental and investigative skills, including safe handling of materials.

• Using scientific data and evidence to solve problems and evaluate methods.

• Communicating effectively using scientific terminology, notation, and conventions.

• Understanding the impact of science on people and the environment.

• Fostering enjoyment and informed interest in science.

The syllabus content covers 12 main 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 structure:

• Core and Extended assessment options, with separate papers for each.

• Core: Paper 1 (Multiple Choice), Paper 3 (Theory), and a practical component (Paper 5 or 6).

• Extended: Paper 2 (Multiple Choice), Paper 4 (Theory), and a practical component (Paper 5 or 6).

• Practical assessment can be a Practical Test or an Alternative to Practical paper.

Assessment objectives and their weightings:

• Knowledge with understanding: 50%

• Handling information and problem-solving: 30%

• Experimental skills and investigations: 20%

Key skills developed:

• Observation, analysis, and safe laboratory practice.

• Application of scientific concepts to new situations.

• Interpretation and evaluation of data, including graphical and numerical information.

• Effective communication of scientific ideas and results.

Sample equations and calculations required:

• Relative atomic mass calculation: Ar=∑(isotope’s relative abundance x relative mass)∑(isotope’s relative abundance)

• General chemical equations and balancing, e.g., H2+O2→H2O

The syllabus encourages the development of transferable skills such as critical thinking, problem-solving, and effective communication, preparing students for further education and employment.

Support resources are available for planning, teaching, assessment, and revision, including specimen papers, mark schemes, and online forums.
