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.
