Cambridge O Level Computer Science helps learners develop an interest in computational thinking and an understanding of the principles of problem-solving using computers. They apply this understanding to create computer-based solutions to problems using algorithms and a high-level programming language. Learners also develop a range of technical skills, and the ability to effectively test and evaluate computing solutions.
Studying Cambridge O Level Computer Science helps learners appreciate current and emerging computing technologies, the benefits of their use and recognise their potential risks. It provides an ideal foundation for progression to Cambridge International AS & A Level and is valuable for other areas of study and everyday life.
The syllabus year refers to the year in which the examination will be taken.
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. Please see the 2023-2025 syllabus document for full details on the changes.
The updated syllabus is for examination from June 2023 onwards. Please see the 2023-2025 syllabus for full details.
We are developing a comprehensive range of materials to help you teach the updated syllabus. These resources will be available from June 2021 onwards (before first teaching) through our School Support Hub and include:
Face-to-face and online training will be available. For up-to-date information, visit our Events and training calendar.

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.
From 2020, we have made some changes to the wording and layout of the front covers of our question papers to reflect the new Cambridge International branding and to make instructions clearer for candidates - learn more.
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).
