What Is IGCSE Biology?
IGCSE Biology is an internationally recognized qualification that introduces students to the fundamental principles of living organisms and the natural world. It is typically taken by students aged 14–16 as part of their secondary education.
The course covers a wide range of topics, including cell biology, genetics, ecology, human physiology, and plant biology, providing a strong foundation for further study in science.
Designed to develop both theoretical knowledge and practical skills, IGCSE Biology encourages learners to understand scientific concepts, analyze data, and apply their learning to real-world situations. Assessment usually includes written examinations and, in some syllabuses, practical experiments.
By studying IGCSE Biology, students gain not only subject expertise but also critical thinking, problem-solving, and research skills that are valuable in higher education and various career paths, from medicine to environmental science.

Cambridge IGCSE Biology (0610) Syllabus & Assessment Overview
The Cambridge IGCSE Biology (0610) syllabus for 2026–2028 offers a comprehensive and globally respected curriculum designed to foster deep scientific understanding and practical skills in learners. This course is aimed at students aged 14-16 years and provides a solid foundation for further study in biology or related subjects.
Key Objectives
The assessment objectives (AOs) for IGCSE Biology encompass various skills and competencies.
- AO1 focuses on demonstrating knowledge and understanding of scientific phenomena, vocabulary, instruments, and applications, while also emphasizing the ability to apply this knowledge in unfamiliar contexts.
- AO2 emphasizes handling information and problem-solving, requiring candidates to locate, organize, and present information, manipulate data, identify patterns, and solve problems.
- Lastly, AO3 emphasizes experimental skills and investigations, including planning experiments, making observations, interpreting data, and evaluating methods.
Candidates are expected to demonstrate proficiency in these areas through written forms of presentation and practical application, preparing them for the challenges of the IGCSE Biology exams.
Extended & Core Content
The Cambridge IGCSE Biology (0610) syllabus is offered at two levels, Core and Extended, to match different learning needs and help students aim for the grades they are best suited to achieve. Both routes cover the same main topics, but the depth and challenge of the content varies.
The Core curriculum is designed for students aiming for grades C–G. It focuses on the essential principles of biology, ensuring a solid understanding of the basics.
Core candidates take Paper 1 (Multiple Choice), Paper 3 (Theory), and either Paper 5 (Practical Test) or Paper 6 (Alternative to Practical). The content is presented in a straightforward way, simplifying complex concepts so learners can master the fundamentals.
The Extended curriculum is aimed at students who wish to access the full grade range A–G*. It includes all Core topics plus extra content, more advanced applications, and a greater emphasis on higher-order thinking.
Extended candidates take Paper 2 (Multiple Choice), Paper 4 (Theory), and either Paper 5 or Paper 6. The questions demand deeper explanations, more complex calculations, and the ability to apply knowledge in unfamiliar contexts, skills that prepare students well for AS/A Level Biology.
Both approaches cover the same subject areas, so students share a common foundation of learning. The main difference lies in the level of detail and exam expectations.
This flexible structure allows schools to choose the most appropriate route for each learner, with the option to move from Core to Extended during the course if progress and confidence grow.
