Cambridge IAL Biology

It includes the main theoretical concepts fundamental to biology, some current applications of biology, and a strong emphasis on advanced practical skills. Cambridge states the emphasis is on understanding concepts and applying biology ideas in novel contexts, as well as acquiring knowledge. Practical skills are assessed in a timetabled practical examination.

Cambridge publishes a 2025–2027 syllabus and a 2028–2030 syllabus. The syllabus year refers to the year in which the examination will be taken, so check which document matches your exam series before planning. The published page does not detail what the 2028–2030 version changes.

Assessment includes a multiple-choice paper, structured questions, and a timetabled practical examination for practical skills. Cambridge notes that Paper 1 Multiple Choice had its duration increased by 15 minutes to allow further reading time, and that Paper 4 A Level Structured Questions no longer has section headings or optional questions.

Cambridge states the updated syllabus is for examination from June 2022 onwards, with examinations available in March 2022 for India only. Changes included clearer learning outcomes, numbered rather than lettered outcomes, shortened aims, revised assessment objectives, and updated command words.

Yes. Cambridge increased the Paper 1 Multiple Choice duration by 15 minutes to allow for further reading time. The source page does not state the resulting total duration, so check the current syllabus PDF for the exact time allowance rather than relying on older figures.

No. Cambridge removed the optional questions from Paper 4 A Level Structured Questions, and section headings were also removed. Treat every part of the paper as compulsory and practise answering full papers without selection strategies, since choosing questions is no longer part of the design.

Follow the syllabus order and use the numbered learning outcomes, which clarify the depth to which each topic should be taught. Note that Cambridge moved some content between AS and A Level, so confirm which stage owns a topic in your syllabus version before revising it.

Practise the underlying techniques rather than memorising descriptions. Cambridge publishes syllabus support including a managing science practicals document and a practical science factsheet. Use these alongside hands-on laboratory experience, since practical skills are assessed in a timetabled practical examination rather than through written recall.

Teachers at registered Cambridge schools can access the School Support Hub, which offers schemes of work, example candidate responses, past papers, specimen paper answers, and digital and multimedia resources. Cambridge also lists endorsed resources from publishers, plus grade descriptions for AS Level and A Level for the 2025–2027 syllabus.

Relying on outdated syllabus details is a frequent problem: outcomes were reworded, content moved between AS and A Level, and command words were updated. Another is ignoring command words, which tell you what the examiner expects. Also avoid treating practical work as theory, since it is separately examined.
