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.
How has the syllabus changed?
To make it easier for teachers to understand what's required, we have:
- updated the learning outcomes, clarifying the depth to which each topic should be taught. Although the wording will look different in many places, the teaching content remains largely the same
- removed and added topics, and moved some content from Cambridge International AS to A Level and vice versa; but the teaching time still falls within the recommended guided learning hours
- numbered the learning outcomes rather than listed by letters
- shortened the syllabus aims and revised the assessment objectives (these changes do not change their meaning or focus)
- updated the list of command words and their meanings to help learners know what's expected of them in the exam.
How has the assessment changed?
- Paper 1 Multiple Choice: duration increased by 15 minutes to allow for further reading time.
- Paper 4 A Level Structured Questions: we have removed the section headings and optional questions.
When do these changes take place?
The updated syllabus is for examination from June 2022 onwards. Examinations are available in March 2022 for India only. Please see the 2022-2024 syllabus above for full details.
