O-Level Mathematics 4052 Syllabus: Topics and Revision Order

For examination in 2026, use Mathematics 4052; for the 2027 G3 examination, use K310. On 12 September 2026 we checked the subject-content sections for indices (N1), simultaneous equations and one-variable inequalities (N7), sets (N8), matrices (N9), similarity and congruence (G2), circles (G3), trigonometry (G4) and statistics (S1) in both documents. The corresponding guides name their sources and limits; this is not a blanket K310 alignment claim. Examination year and later admissions year are different. Our 18 topic guides are search groupings, not a claim to cover all 18 official syllabus topics.

The 2026 O-Level Mathematics 4052 syllabus is the official source of examinable scope. It helps students and parents see the topic areas and assessment expectations. But a syllabus is not a personalised revision plan.

Two students can both be weak in graphs for different reasons. One may need coordinate geometry. Another may need algebraic manipulation. Another may need calculator and scale-reading habits. The topic list is the starting point, not the full diagnosis.

A useful way to read the syllabus is by strands. Number skills support percentages, ratio, proportion, and measurement. Algebra supports equations, graphs, factorisation, and functions. Geometry supports angle properties, congruence, similarity, trigonometry, and mensuration.

When a later topic keeps failing, inspect the strand underneath it. The repair may be several chapters earlier.

Start with high-dependency skills: arithmetic accuracy, algebraic manipulation, equations, ratios, and basic geometry. Then move into topic families such as graphs, trigonometry, similarity, and mensuration. Finally, use mixed exam-style questions to practise choosing methods without topic labels.

This order is not fixed for everyone. If a diagnostic shows that a student is secure in algebra but weak in geometry, the revision path should shift. The best order is the one that repairs the earliest blockers first.

Mentora treats topics as connected skills. If a student struggles with a harder question, the system can route them to the prerequisite skill instead of simply giving another similar hard question.

That matters because exam readiness is not only about covering chapters. It is about whether the skills underneath each question are stable enough to use under pressure.
