See sample questionsG3 Computing is a Singapore secondary-school Computing subject. Students learn Computing Fundamentals, Algorithms and Programming, Spreadsheets, Networking and Impact of Computing.
G3 Computing is the Computing subject under Singapore's Secondary Education Certificate framework from 2027. It follows the former GCE O-Level Computing subject, with many familiar areas including Python programming, spreadsheets, networking and computing fundamentals. See our detailed comparison.
Yes. Python is used for programming in G3 Computing. Students learn to read and trace code, develop programs, test their solutions and debug errors.
Past O-Level Computing questions can remain useful where the underlying knowledge and skills are relevant to G3 Computing. They can help students understand question types and practise applying concepts, while practice should also be checked against the current syllabus. Explore our past-year sample question guide.
