IGCSE Biology Syllabus and Exam Pattern (2026–2028): Complete Cambridge 0610 Guide
If you are teaching, studying, or planning entry for Cambridge IGCSE Biology, this guide gives you the full picture in one place. It covers the official 0610 syllabus, the exam pattern, Core vs Extended, practical papers, assessment objectives, and the best way to revise around the real paper structure.
Instead of relying on school rumours or incomplete notes, this guide follows the official Cambridge syllabus for exams in 2026, 2027, and 2028.
- Updated for 2026–2028 syllabus
- Based on official Cambridge structure
- Covers students, teachers, and schools
21 Topics
The Cambridge IGCSE Biology 0610 syllabus includes 21 topic areas, from classification and cells to ecology and biotechnology.
3 Components
Students take one multiple-choice paper, one theory paper, and one practical component.
Core vs Extended
Core candidates are eligible for grades C to G, while Extended candidates are eligible for grades A* to G.
Quick Answer
Cambridge IGCSE Biology 0610 for 2026–2028 covers 21 topics, from cell biology and enzymes to inheritance, ecology, and biotechnology. Students take three components: a multiple-choice paper, a theory paper, and either a Practical Test or an Alternative to Practical paper. Core candidates take Papers 1 and 3, while Extended candidates take Papers 2 and 4; both routes then take either Paper 5 or Paper 6. The official weighting is 30% for multiple choice, 50% for theory, and 20% for practical assessment.
This summary reflects the official Cambridge 0610 assessment overview.

What this guide covers
Many students collect notes, rely on old school advice about the paper pattern, and only discover the actual Cambridge assessment structure late in the session. That usually leads to weak planning and wasted revision time.
The official Cambridge documents are much clearer. Cambridge IGCSE Biology 0610 for 2026, 2027, and 2028 is a structured science course with 21 topic areas, three assessed components, a clear Core and Extended split, and a strong practical-skills requirement.
For schools and teachers, this matters because Biology does not reward memorisation alone. The assessment objectives show that students are tested on knowledge, application, data handling, and practical understanding together.
What is Cambridge IGCSE Biology 0610?
Cambridge IGCSE Biology 0610 is part of the Cambridge Upper Secondary programme. The syllabus is designed to help learners understand key biological ideas, develop scientific thinking, and build practical skills for further study.
Cambridge also states that IGCSE syllabuses are designed to require about 130 guided learning hours. That shows the scale of the course: Biology 0610 is a full academic science subject, not a light overview.
Which syllabus years does this guide apply to?
This guide is based on the official Cambridge IGCSE Biology 0610 syllabus for examinations in 2026, 2027, and 2028. Cambridge states that exams are available in the June and November series, and also in the March series in India.

How to understand the syllabus as a teacher or student
The best way to read the Cambridge Biology syllabus is not as 21 isolated chapters. It makes more sense when grouped into teaching blocks.
The first block builds the foundation of the subject through classification, cell structure, transport across membranes, biological molecules, and enzymes. The middle of the course focuses on plant and human physiology. Later sections move into reproduction, inheritance, variation, ecology, and biotechnology.
Students who understand how these topics connect usually perform better than students who memorise each chapter separately.
Core route
Core candidates take Paper 1 and Paper 3, plus either Paper 5 or Paper 6. Cambridge states that candidates taught only the Core content are eligible for grades C to G.
This route is suitable for students who are not being entered for the highest grade band.
Extended route
Extended candidates take Paper 2 and Paper 4, plus either Paper 5 or Paper 6. Cambridge states that candidates entered for Extended are eligible for grades A* to G.
This route includes the Core content plus the Supplement and should be chosen early enough for proper teaching.
Important: A student entered on the Core route cannot later achieve an A* in syllabus 0610, because the entry route itself limits the available grade range.
Cambridge IGCSE Biology exam pattern in detail
| Component | Candidate route | Duration | Marks | Weighting | What it tests |
|---|---|---|---|---|---|
| Paper 1: Multiple Choice | Core | 45 minutes | 40 | 30% | AO1 and AO2 |
| Paper 2: Multiple Choice | Extended | 45 minutes | 40 | 30% | AO1 and AO2 |
| Paper 3: Theory | Core | 1 hour 15 minutes | 80 | 50% | AO1 and AO2 |
| Paper 4: Theory | Extended | 1 hour 15 minutes | 80 | 50% | AO1 and AO2 |
| Paper 5: Practical Test | All candidates | 1 hour 15 minutes | 40 | 20% | AO3 |
| Paper 6: Alternative to Practical | All candidates | 1 hour | 40 | 20% | AO3 |
Why the practical paper matters more than students think
Many students assume that Alternative to Practical means practical work can be ignored. That is a mistake.
Cambridge clearly states that Paper 5 and Paper 6 require the same experimental skills, require understanding of the same experimental contexts, and test the same assessment objective, AO3. Even students taking Paper 6 still need proper practical preparation.
Assessment objectives: what Cambridge is really testing
Cambridge divides the qualification into three assessment objectives.
AO1 covers knowledge with understanding.
AO2 covers handling information and problem-solving.
AO3 covers experimental skills and investigations.
| Assessment objective | Weighting |
|---|---|
| AO1 Knowledge with understanding | 50% |
| AO2 Handling information and problem-solving | 30% |
| AO3 Experimental skills and investigations | 20% |
How students should revise based on the real exam pattern
Revise MCQs for speed
Paper 1 or 2 is fast and time-pressured. Students need quick recall, sharp diagram reading, and strong elimination skills.
Practise written answers
Paper 3 or 4 carries the largest weighting, so students must write structured biological answers instead of only reading notes..
Train practical skills
For Paper 5 or 6, students should practise graphs, variables, biological drawings, magnification, observations, and method improvements.
Common mistakes teachers and students should avoid
- Treating Core and Extended as a small difference
- Ignoring practical work because of Paper 6
- Teaching isolated notes without linking concepts
- Delaying past paper practice
- Chasing fixed percentages instead of understanding thresholds
Grade thresholds are published by Cambridge for each exam series and can vary by option combination. That is why students should use official threshold tables for the exact session instead of relying on fixed-percentage myths.
Frequently asked questions
What is the exam pattern of IGCSE Biology?
IGCSE Biology has three components: one multiple-choice paper, one theory paper, and one practical component chosen from either Practical Test or Alternative to Practical. Core and Extended candidates take different MCQ and theory papers, but both practical routes carry the same weighting.
What is the difference between Core and Extended in IGCSE Biology?
Core candidates study the Core content only and are entered for Papers 1 and 3, while Extended candidates study Core plus Supplement content and are entered for Papers 2 and 4. Cambridge states that Core candidates are eligible for grades C to G, while Extended candidates are eligible for grades A* to G.
Is Alternative to Practical easier than the Practical Test?
Cambridge does not present it as easier. The syllabus says Paper 5 and Paper 6 require the same experimental skills, the same experimental contexts, and test the same assessment objective, AO3.
Are calculators allowed in IGCSE Biology?
Yes. Cambridge states that calculators may be used in all parts of the exam.
