O-Level Additional Mathematics (A-Math) Summary

Free O-Level Additional Mathematics summary covering algebra, trigonometry, calculus, geometry and exam-focused revision.

What it is: A 40-page GCE O-Level Additional Mathematics summary covering the full A-Math syllabus – simultaneous and quadratic equations, indices, surds, exponentials and logarithms, the binomial theorem, partial fractions, remainder and factor theorem, coordinate geometry, linear law, trigonometry and circular functions, differentiation and integration with their applications, kinematics, and plane geometry (O-Level only).
Why you need it: O-Level A-Math is one of the most demanding subjects in the Express stream and a key foundation for A-Level Maths. This summary distils every method and formula into one structured revision document aligned to the Singapore-Cambridge examination.
Who it’s for: Secondary Express stream students preparing for GCE O-Level Additional Mathematics in Singapore, plus their parents and tutors.
How it helps: By organising the syllabus into worked methods and formulae – with O-Level-only topics such as plane geometry clearly flagged – it helps students master techniques, target weak areas and revise efficiently for Papers 1 and 2.

This comprehensive GCE O-Level Additional Mathematics summary sheet covers the full Singapore-Cambridge A-Math syllabus, bringing together essential formulas, concepts and problem-solving techniques into a single revision resource. Designed for efficient study and examination preparation, it provides students with a structured reference guide covering every major topic. Topics include simultaneous and quadratic equations, indices, surds, exponentials and logarithms, the binomial theorem, partial fractions, the remainder and factor theorem, coordinate geometry, linear law, trigonometry, circular functions, differentiation, integration, kinematics and plane geometry. By consolidating key methods and formulas into one organised document, this resource helps students strengthen mathematical fluency, improve problem-solving confidence and prepare effectively for examinations.
