Syllabus updates

Syllabus changes
- 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.
