What is IGCSE Combined Science? | Complete Guide to Curriculum, Exam Format, and Further Study
TUTORZONE SUBJECT GUIDE · IGCSE
IGCSE Combined Science folds Biology, Chemistry and Physics into a single integrated Cambridge qualification. This complete guide walks through its curriculum, exam format and grading, and explains how it sets you up for A-Levels, the IB and beyond.
Direct Answer：What is IGCSE Combined Science?
IGCSE Combined Science is a single Cambridge qualification that integrates Biology, Chemistry, and Physics into one course.
What Is IGCSE Combined Science?
IGCSE Combined Science is a science subject offered by the Cambridge Assessment International Education (CAIE) for students aged 14 to 16. This course combines Biology, Chemistry, and Physics into a single, integrated curriculum. It is ideal for students interested in science but not planning to take all three sciences separately. The course builds a solid foundation for future studies such as A-Levels or the IB Diploma Programme.
Curriculum Content
Biology
- Cell structure and function
- Nutrition and the digestive system
- Respiration and the circulatory system
- Reproduction and genetics
- Ecosystems and environmental protection
Chemistry
- Atomic structure and the periodic table
- Chemical bonding and molecular structure
- Acids, bases, and neutralization
- Reaction rates and energy changes
- Basic organic chemistry
Physics
- Force and motion
- Energy, work, and power
- Heat transfer and thermal energy
- Electricity and magnetism
- Waves (sound and light)
The Combined Science curriculum is concise and focused, covering the fundamental concepts across all three science subjects, helping students build scientific literacy.
Exam Structure and Assessment
The Cambridge IGCSE Combined Science assessment typically includes the following papers:
| Paper | Type | Duration | Marks |
|---|---|---|---|
| Paper 1 | Multiple Choice | 45 minutes | 40 |
| Paper 3 | Structured Questions | 1 hr 15 mins | 80 |
| Paper 5 or 6 | Practical or Alternative to Practical | 1 hour | 40 |
Students can choose either the Core (grades C to G) or Extended (grades A* to E) level based on their ability and academic goals.
Further Study and Career Relevance
Who should take Combined Science?
Enjoys Science
Students who enjoy science but prefer not to take three separate science subjects.
Non-STEM Pathway
Those planning to pursue non-STEM university courses (e.g., business, arts, humanities).
Balanced Schedule
Students who want a balanced schedule across subjects.
Where is it recognized?
- Entry-Level Qualification——for A-Level or IB science (varies by school).
- Widely Accepted——by universities in the UK, USA, Australia, and Canada.
- International Value——provides international academic value.
Study Tips and Resources
- Plan by Topic——set weekly goals by topic, such as “Cells and Tissues,” “Chemical Reactions,” or “Forces and Motion.”
- Practise Past Papers——to become familiar with question styles and timing.
- Make Summary Notes——create summary notes and charts for formulas and key concepts.
- Use Quality Resources——such as the Cambridge textbooks, Physics & Maths Tutor, and Save My Exams.
Expert Tips
- Heading to A-Level Sciences?——if you aim to study A-Level Biology, Chemistry, or Physics, it’s recommended to take the full single-science subjects instead.
- A Solid Foundation——Combined Science is a solid choice for students with weaker math/science skills who still want a basic science foundation.
- Pick the Right Tier——choose the Core level if aiming for a moderate grade, or Extended level if targeting an A or A*.
Frequently Asked Questions (FAQ)
Q: Is Combined Science enough for A-Level sciences?
If you plan to study A-Level Biology, Chemistry or Physics in depth, it is usually better to take the full single-science IGCSEs instead. Combined Science covers the fundamentals but in less depth than the separate subjects.
Q: What grades can I achieve?
The Core tier is graded C to G, while the Extended tier is graded A* to E. Choose Extended if you are targeting an A or A*.
Q: How many exam papers do I need to sit?
Typically three components — a multiple-choice paper, a structured-questions paper, and a practical or alternative-to-practical paper.
Q: Is Combined Science accepted by universities?
Yes. It is widely accepted as an entry-level science qualification by universities in the UK, USA, Australia and Canada, particularly for non-STEM degree programmes.
