H3 Mathematics 2026 - Syllabus, Exam Format, Who Qualifies

Q: What does H3 Math in A-Level: 2026 Guide cover?
A: What parents and Integrated-Programme students need to know about H3 Math: how it builds on H2, who should take it, syllabus structure, assessment formats.

TL;DR
H3 Mathematics (syllabus 9820, first examined 2025) is a proof-heavy extension to H2.
Candidates sit one compulsory 3-hour paper marked out of 80 with six questions (Q6 includes reading/responding to a mathematical text).
Selection is school-based; H3 is graded Distinction/Merit/Pass/Ungraded on the A-Level certificate but is not counted in the 70-point University Admission Score (UAS).
This guide maps the syllabus, flags hidden cliffs, and shows how to bridge the leap from H2 procedures to H3 proof writing.

For the full H2 foundation sequence that H3 builds on, keep our H2 Maths Notes hub nearby.

If you are still checking whether the H2 base is stable enough, use our H2 Maths tuition Singapore page as a checklist for Paper 1 and Paper 2 pacing, working clarity, and calculator habits before stretching further.

Status: SEAB's current H3 Mathematics (9820) syllabus PDF is labelled for 2026. The scheme remains one 3 h, 80-mark paper with six compulsory questions; Q6 includes a reading-and-response task.

• H3 Maths is proof-heavy extension work: Check whether H2 Maths is already stable.
• It does not add to the UAS, but it signals mathematical depth: Decide whether the extra workload serves your goal.
• The main challenge is reasoning clearly under time pressure: Practise writing complete proof steps, not just finding ideas.

Concrete example: If you can solve a problem mentally but cannot explain each implication on paper, H3 will expose that gap quickly.

Proof-readiness checkpoint

Before choosing H3, test whether your working already explains the reason behind each step. H3 questions often reward the bridge between an idea and a complete argument, not just the final observation.
