IGCSE Combined Science 0653: Syllabus, Tips and How to Revise
IGCSE Combined Science 0653 (Co-ordinated Sciences) is the Cambridge IGCSE that combines Biology, Chemistry, and Physics into one qualification. It is widely searched by students who want a broad science base without taking three separate sciences, or who are following a combined pathway at school.
IGCSE Combined Science 0653 at a Glance
- Three sciences in one – Biology, Chemistry, and Physics content across several papers.
- Core and Extended – Tier choice affects grades available (Core C–G, Extended A*–E).
- Practical – Often an alternative-to-practical or practical component; check your syllabus.
Revision should balance all three subjects and use the syllabus to avoid missing topics.
Revision Tips for IGCSE Combined Science 0653
- Split revision by subject – Use separate revision sessions for Biology, Chemistry, and Physics.
- Learn key definitions and formulae for each science – They are often tested directly.
- Practise past papers for each science component so you are used to the mix of question types.
- Use a checklist so you cover every topic across the three sciences.

How Combined Science 0653 Is Assessed and Common Mistakes
The syllabus combines Biology, Chemistry, and Physics across several papers; the exact structure is in the syllabus. You need to balance revision across all three sciences and use a topic checklist so you do not miss any area. Common mistakes: Focusing on one science and neglecting the others; not learning key definitions and formulae for each subject; treating it as one subject (the mark schemes and question styles differ by science—practise each separately as well as in combined format); running out of time (practise full papers to build pace across all three).
