Cambridge IGCSE Biology helps learners to understand the biological world in which they live and take an informed interest in science and scientific developments. The syllabus includes the basic principles and concepts that are fundamental to the subject, some current applications of biology, and a strong emphasis on practical skills.
Learners also develop an understanding of the scientific skills essential for progression to Cambridge International AS & A Level, further education or a career related to science.
From 2020 examination this syllabus will no longer be regulated by the qualifications and examinations regulators in England, Wales and Northern Ireland. Changes to the syllabus and specimen papers reflect the change in regulated status. This syllabus will continue to be available worldwide.
Please note that if you make an entry for the A*-G grading scale, it is not then possible to switch to the 9-1 grading scale once the entries deadline has passed. If you find that you have accidentally made an entry for the A*-G syllabus, you must withdraw and re-enter before the entries deadline.

We revise our qualifications regularly to make sure that they continue to meet the needs of learners, schools and higher education institutions around the world and reflect current thinking. The new syllabus is clearer and more consistent across the three sciences. This is helpful for teachers who are teaching more than one science syllabus, and students who will enjoy a more coherent experience across each science. Please see the 2023-2025 syllabus document for full details on the changes.
There are no assessment changes.
The updated syllabus is for examination from June 2023 onwards. Examinations are available in March 2023 for India only. Please see the 2023-2025 syllabus for full details.
