What K310 and 4052 mean
2027 examination · K310
G3 Mathematics under the Singapore-Cambridge Secondary Education Certificate
If your examination entry says Mathematics K310, use the 2027 K310 syllabus.
2026 examination · 4052
Mathematics under the Singapore-Cambridge GCE O-Level
If your examination entry says Mathematics 4052, use the 4052 syllabus for that examination year. SEAB's 2027 directory lists 4052 as the reference code for 2026 and earlier.

What we checked
We compared these five points in the official 2026 4052 and 2027 K310 PDFs. Some details match, but that does not mean the two syllabuses are identical. For anything not shown here, check the syllabus for your examination year and code.
| Checked point | 2026 · 4052 | 2027 · K310 | What this means |
|---|---|---|---|
| Certificate and subject code | 2026 Singapore-Cambridge GCE O-Level Mathematics, 4052 | 2027 Singapore-Cambridge Secondary Education Certificate G3 Mathematics, K310 | The subject code and certificate name change. |
| Assessment-objective weighting | AO1 45% · AO2 40% · AO3 15% | AO1 45% · AO2 40% · AO3 15% | The published AO weightings are the same. |
| Paper 1 | 2 h 15 min · about 26 short-answer questions · 90 marks · 50% | 2 h 15 min · about 26 short-answer questions · 90 marks · 50% | No change in the published Paper 1 format. |
| Paper 2 | 2 h 15 min · 9–10 questions · final real-world-context question · 90 marks · 50% | 2 h 15 min · 9–10 questions · final real-world-context question · 90 marks · 50% | No change in the published Paper 2 format. |
| Calculator and formulae | Calculator used for both papers; formulae provided on page 2 of each question paper | Calculator used for both papers; formulae provided on page 2 of each question paper | Both documents state that calculators are used for both papers and formulae are provided. |
Which syllabus should you use?
Taking the exam in 2027?
Check K310. Use a Mentora guide for K310 only where that guide names a specific K310 syllabus reference.
Taking O-Level Mathematics in 2026 or earlier?
Check 4052. Mentora's topic pages keep their existing URLs and their stated 4052 scope.
If you are unsure, use the code shown by your school or exam registration. School level alone is not enough to identify the right syllabus.
Mentora guides checked against both syllabuses
We checked the relevant scope of these nine Mentora guides against both official documents. They are Mentora learning groupings rather than official SEAB topic names, and they are not a complete syllabus crosswalk.
