Cambridge IGCSE Combined Science

Summary of course content

Cambridge IGCSE Combined Science covers key concepts in biology, chemistry, and physics. Enhance your scientific understanding and skills.

In this Cambridge IGCSE Combined Science course, you will understand the biological and technological aspects of life and make a dive into the principles and concepts that are fundamental to science. Learn skills that have utility in everyday life and encourage you to take a new look at solving problems in real life.

Begin exploring the interconnected world of science today.

This course aims to:

  • provide an enjoyable and worthwhile educational experience for all learners, whether or not they go on to study science beyond this level
  • enable learners to acquire sufficient knowledge and understanding to:
    •  become confident citizens in a technological world and develop an informed interest in scientific matters
    •  be suitably prepared for studies beyond Cambridge IGCSE
  • allow learners to recognise that science is evidence-based and understand the usefulness, and the limitations of scientific method
  • develop skills that:
    • are relevant to the study and practice of science
    • are useful in everyday life
    • encourage a systematic approach to problem-solving
    • encourage efficient and safe practice
    • encourage effective communication through the language of science
  • develop attitudes relevant to science such as:
    •   concern for accuracy and precision
    •   objectivity
    •   integrity
    •   enquiry
    •   initiative
    •   inventiveness
  • enable learners to appreciate that:
    • science is subject to social, economic, technological, ethical and cultural influences and limitations
    • the applications of science may be both beneficial and detrimental to the individual, the community and the environment.

Guided Learning Hours

We design Cambridge IGCSE syllabuses based on learners having about 130 guided learning hours for each subject during the course but this is for guidance only. The number of hours a learner needs to achieve the qualification may vary according to local practice and their previous experience of the subject.
