Cambridge O Level Biology (5090)

Syllabus overview

Cambridge O Level 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.

Syllabuses

The syllabus year refers to the year in which the examination will be taken.

Syllabus updates

  • Summary of the changes
    • 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. We have updated this syllabus and all assessment materials so they are 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.

      What are the main changes to the syllabus?

      To support teachers and learners, we have:
      • updated the learning objectives to demonstrate the depth you should teach each topic. The wording looks different in many places, but the teaching content remains largely the same
      • updated the topic structure to make sure topics and sub-topics are clearly linked
      • removed and added topics; making sure that the teaching time is still within the guided learning hours
      • included a list of mathematical requirements to support teaching and learning.

      What are the main changes to the assessment?

      • We have removed Section B (optional questions) in Paper 2. There are no separate sections to the paper and all questions are compulsory.
      • We have increased the duration of Paper 3.
      • Paper 6 is now called Paper 4. This paper has a similar structure to Paper 3, making sure there is consistency between the two papers that assess practical skills.

      When do these changes take place?

      The updated syllabus is for examination from June 2023 onwards. Please see the 2023-2025 syllabus for full details.

  • Teaching and learning resources

Important notices

  • Cambridge Upper Secondary Science competition
    • Find out more about our competition for Cambridge IGCSE students aged 14-16.

  • Grade descriptions
    • For some subjects, the syllabus states that Grade Descriptions will be made available after first assessment in 2020, 2021 or 2022.

      Publication of grade descriptions was paused in response to the Covid-19 pandemic and the temporary changes to the grading standard that have been in place for 2020, 2021 and 2022. We are currently working on producing these grade descriptions. This work will make sure that grade descriptions reflect examination outcomes appropriately and are based on the more stable grading standard that we expect to have in place for June 2023 onwards.

School Support Hub

We provide a wide range of support so that teachers can give their learners the best possible preparation for Cambridge programmes and qualifications.
