What officially changes in 2027?
The clearest change is the qualification framework and subject code. In 2026, the subject is Singapore-Cambridge GCE O-Level Computing 7155. From 2027, it is assessed under the Singapore-Cambridge Secondary Education Certificate (SEC) as G3 Computing K349.
| Area | 2026 | 2027 | Status |
|---|---|---|---|
| Qualification | GCE O-Level | SEC G3 | Changed |
| Subject code | 7155 | K349 | Changed |
| Subject title | Computing | G3 Computing | Changed framing |
What stays broadly familiar?
The subject remains a combination of computing knowledge and practical problem solving. Students still need to understand computing fundamentals, write and reason about Python programs, work with spreadsheets, understand networks, and consider the impact of computing.
Is the practical exam still there?
Yes. K349 has a two-hour written Paper 1 worth 60% and a 2 hour 30 minute lab-based Paper 2 worth 40%. Paper 2 assesses Algorithms & Programming and Spreadsheets using a computer with spreadsheet software, Python and JupyterLab.
Does my child need a different programming language?
No. Python remains the programming language specified in K349.
Can students still use O-Level Computing practice questions?
Many older 7155-style questions can remain useful where the underlying skill is still in K349, especially programming, tracing, debugging and spreadsheet problem solving. Students should still check each question against the current K349 syllabus rather than assuming every old topic remains examinable.
What should parents take away?
The new K349 label matters, but parents do not need to treat G3 Computing as an entirely unfamiliar subject. The more useful question is whether a student can apply what they know: read code, trace it, debug it, and construct solutions independently.
