Cambridge International AS and A Level Biology builds on the skills acquired at Cambridge IGCSE (or equivalent) level. The syllabus includes the main theoretical concepts which are fundamental to the subject, some current applications of biology, and a strong emphasis on advanced practical skills. Practical skills are assessed in a timetabled practical examination.
The emphasis throughout is on the understanding of concepts and the application of biology ideas in novel contexts as well as on the acquisition of knowledge. The course encourages creative thinking and problem-solving skills which are transferable to any future career path. Cambridge International AS and A Level Biology is ideal for learners who want to study biology or a wide variety of related subjects at university or to follow a career in science.
The syllabus year refers to the year in which the examination will be taken.
We revise qualifications regularly to make sure that they continue to meet the needs of learners, schools and higher education institutions around the world and that they are up-to-date with current thinking. We have updated this syllabus and all assessment materials to improve the clarity and consistency between Biology, Chemistry and Physics.

For some subjects, we publish grade descriptions to help understand the level of performance candidates’ grades represent.
We paused the publication of grade descriptions in response to the Covid-19 pandemic and the temporary changes to the awarding standard in 2020, 2021 and 2022.
As the awarding standard has now returned to the pre-pandemic standard, we are working to produce up-to-date grade descriptions for most of our general qualifications. These will be based on the awarding standards in place from June 2023 onwards.
We provide a wide range of support so that teachers can give their learners the best possible preparation for Cambridge programmes and qualifications. For teachers at registered Cambridge schools, support materials for specific syllabuses are available from the School Support Hub (username and password required).
Use our videos and teaching materials to deliver engaging lessons and explain challenging topics and skills to your learners.
