Cambridge IGCSE Combined Science gives learners the opportunity to study Biology, Chemistry and Physics, each covered in separate syllabus sections. It is a single award qualification, earning one grade.
The syllabus year refers to the year in which the examination will be taken.
We have updated Cambridge IGCSE Combined Science to make sure that it continues to reflect current educational thinking and meet the needs of learners, schools and higher education institutions around the world. We have made the new syllabus clearer and more consistent with the single sciences. This is helpful for teachers who are teaching more than one science syllabus, and students who will enjoy a more coherent experience across each science.
For full details of the changes, please see the 2025-2027 syllabus above.
We are developing a comprehensive range of resources to help teachers deliver this updated syllabus.
We aim to provide a scheme of work and other relevant classroom resources. Example Candidate Responses will be available following the first examination in 2025.
Visit the School Support Hub from June 2025 onwards for details.
