Have there been many changes to the new Co-ordinated Sciences 0645 syllabus for 2025 to 2027?

IGCSE Co-ordinated Sciences 0654 syllabus has been redeveloped for assessment in 2025-27. It is therefore important that you read the whole syllabus before planning your course. There is a ‘Transition Guide’ on the School Support hub here to support teachers in their planning and shows how learning objectives, notes and examples compare between the content taught for assessment in 2023-24 against the content required for the new 2025-27 syllabus.
