What is IGCSE Chemistry?

2025-06-03

IGCSE Chemistry (International General Certificate of Secondary Education – Chemistry) is an international secondary school chemistry course offered by Cambridge Assessment International Education (CAIE), designed for students aged 14 to 16. The course aims to develop students’ fundamental understanding of the structure, properties, and changes of matter, while cultivating scientific inquiry and practical laboratory skills. It provides a solid foundation for further studies in A-Level, IB, and university-level science programs.

Core Topics of the IGCSE Chemistry Curriculum

1. Structure of Matter and the Periodic Table

Atomic structure and electron configuration
Periodic table and its trends
Molecular structure and chemical bonding (covalent, ionic, etc.)

2. Principles of Chemical Reactions

Writing and balancing chemical equations
Acid-base reactions and the concept of neutralisation
Redox reactions and their applications
Reaction rates and the concept of chemical equilibrium

3. Fundamentals of Organic Chemistry

Hydrocarbons and isomerism
Identification of organic functional groups
Basic types of organic reactions

4. Practical Skills

Experimental design and lab techniques
Measurement errors and data processing
Laboratory safety guidelines

IGCSE Chemistry Exam Structure

Paper 1: Multiple Choice (45 minutes, 40 marks)
Paper 2: Structured Questions (1 hour 15 minutes, 80 marks)
Paper 3: Practical Test (optional) (1 hour 15 minutes, 40 marks)
Paper 4: Alternative to Practical (optional) (1 hour, 40 marks)

The exams assess both theoretical knowledge and practical skills. Grades range from A* to G, and students may select papers based on their academic goals.
