Which IGCSE Science to Choose UAE 2026 — Physics, Chemistry, Biology or Combined Science?
Choosing which IGCSE science subjects to take is one of the most consequential Year 9 decisions for UAE students on any university pathway — but especially for students considering Medicine, Engineering, or Science degrees. A student who chooses the wrong combination at IGCSE may find their A-Level or IB Diploma options limited, or find that a required A-Level science has content gaps because the IGCSE foundation was not taken. This guide covers the specific decision framework for UAE families.

Which Two Sciences — For Students Not Taking All Three
For UAE students taking two sciences (not all three), the choice depends on intended university pathway:
|
Intended
Pathway |
Priority
Sciences |
Why |
|
Medicine (UK,
UAE, International) |
Chemistry +
Biology (both essential) |
A-Level/IB
Chemistry HL and Biology HL are required for all UK and UAE medical school
applications — both IGCSE foundations are essential |
|
Engineering
(Mechanical, Civil, Electrical) |
Physics +
Chemistry (Maths is also critical) |
A-Level
Physics and Mathematics are the Engineering priority; Chemistry is required
for Chemical Engineering specifically; Biology is generally not needed |
|
Computer
Science / AI / Data Science |
Physics +
Mathematics (CS more than Biology) |
None of the
three sciences is specifically required for CS degrees; Physics and
Mathematics most strongly support computational thinking |
|
Business /
Economics / Law |
Any one
science (personal choice) |
Business,
Economics, and Law do not require specific science IGCSEs; one science
confirms scientific literacy broadly |
|
Undecided |
Physics +
Chemistry or all three |
Physics +
Chemistry opens Engineering and Science pathways; adding Biology opens
Medicine; all three keeps all options open |
The Three Sciences Compared — A Parent's Quick Guide
IGCSE Physics (Cambridge 0625)
Most mathematical of the three sciences. Requires equation application, unit analysis, and algebraic rearrangement. Most marks come from calculation questions and "explain" questions requiring cause-effect chains. Students who enjoy Maths and find formulae satisfying tend to find Physics the most manageable science. Most challenging for students who struggle with mathematical precision under timed conditions.
IGCSE Chemistry (Cambridge 0620)
Broadest content coverage. Requires both mathematical precision (mole calculations, pH calculations) AND large content breadth (organic chemistry reaction types, qualitative analysis, electrochemistry). Paper 6 Alternative to Practical requires knowledge of specific practical techniques. Generally considered the hardest of the three IGCSE sciences by most UAE students and tutors — but also the most commonly required for university pathways.
IGCSE Biology (Cambridge 0610)
Most content-heavy of the three sciences. Requires memorising a large body of terminology, knowing specific diagrams (mitosis stages, leaf cross-section, kidney nephron, heart, digestive system) from memory, and using precise mark-scheme language in every response. Students who are systematic memorisers and enjoy understanding living systems tend to find Biology the most accessible science — but it consistently requires more memorisation time than Physics or Chemistry.
What Schools in UAE Typically Offer
Most UAE British curriculum schools (Repton, Brighton College, GEMS Wellington, Kings, Cranleigh, Dubai College, Nord Anglia) offer three separate IGCSE Sciences as the standard track for Year 10-11 students. Combined Science is a less common option at these schools — typically available for students for whom the three-science workload is inappropriate. Schools with a very wide IGCSE subject offering may allow students to drop one science by Year 10 if their pathway does not require it.

Frequently Asked Questions
Q: Should UAE students take three separate IGCSE Sciences or Combined Science?
Three separate Sciences for students intending A-Level or IB HL Science (Medicine, Engineering, Science degrees). Combined Science for students not planning to continue sciences at A-Level/IB, reducing workload for non-science pathway students.
Q: Is Physics or Biology harder in IGCSE?
Differently demanding. Physics requires mathematical fluency (most marks from calculations). Biology requires systematic memorisation (large content breadth, mark-scheme language precision). Chemistry requires both — most UAE students find Chemistry hardest.
Q: Which IGCSE science is most important for A-Level or IB HL science?
Each IGCSE Science is an essential prerequisite for its A-Level/IB equivalent. For Medicine: both Biology and Chemistry. For Engineering: Physics and Chemistry. For CS: none specifically required. All three Sciences keeps all options open.
Q: What is IGCSE Combined Science and how does it compare to separate Sciences?
Combined Science covers Physics, Chemistry, and Biology in 2 papers instead of 6, producing 2 IGCSE grades instead of 3. Less depth than separate Sciences — students who then choose separate Science A-Levels may have content gaps compared to peers who took separate IGCSE Sciences.
Q: Can UAE students choose just two IGCSE Sciences?
Yes — Medicine track: Chemistry + Biology (both required for A-Level/IB applications). Engineering track: Physics + Chemistry. CS/other: Physics + any science, or one science only. Undecided: all three keeps all options open.
