About iGCSE Combined Science

iGCSE Combined Science (also known as Co-ordinated Sciences) allows students to study biology, chemistry and physics within a single qualification. Offered by Cambridge International, it is designed for students who want a broad scientific education without taking three separate science iGCSEs.

The qualification is assessed through written papers covering all three science disciplines. Students take a combination of multiple-choice, structured and practical-based written questions. The Core/Extended structure allows the course to be accessible to all ability levels while still challenging the most able students. Combined Science typically results in a single or double award grade.

This qualification is ideal for students who enjoy science but intend to specialise in non-science subjects at A-Level. It provides a solid foundation in scientific literacy, experimental skills and analytical thinking, and is accepted by universities worldwide as evidence of broad scientific competence.

Study Tips for Combined Science

✓ Create a revision timetable that allocates equal time to biology, chemistry and physics sections. Students often neglect their weakest science, which drags down the overall grade.
✓ Use colour-coded notes to separate the three disciplines, making it easier to organise your revision and quickly locate key information.
✓ Focus on the connections between the three sciences - for example, how energy transfer links physics (thermal energy), chemistry (energetics) and biology (respiration).

Exam Tips for iGCSE Combined Science

✓ In the exam, identify which science discipline each question relates to before answering, and use the correct specialist vocabulary for that discipline.
✓ Manage your time carefully across the paper. Combined Science papers cover a lot of content, so do not spend too long on any single question.
✓ For calculation questions, always show your working and include units. The mark scheme awards method marks across all three science areas.

Frequently Asked Questions

What is iGCSE Combined Science? +

iGCSE Combined Science (Co-ordinated Sciences) is a qualification that covers biology, chemistry and physics in a single course, resulting in one or two iGCSE grades. It is offered by Cambridge International for students who want broad scientific knowledge without taking three separate sciences.

Can I do A-Level sciences after iGCSE Combined Science? +

It depends on the school and the specific A-Level. Some schools accept a strong grade in Combined Science for progression to a single A-Level science, but many prefer students to have taken the separate science iGCSEs. Check with your school for their specific policy.

Is Combined Science easier than separate sciences? +

Combined Science covers less depth in each discipline than the separate iGCSEs but spans all three sciences. Students who excel in one science but struggle in others may find the combined approach more challenging overall, as the grade reflects performance across all three areas.
