Pearson Edexcel International GCSE Mathematics A (Modular) is a separate assessment route from the familiar linear Mathematics A 4MA1 qualification. Pearson introduced the modular route for first teaching in 2024, with external assessment and certification available from 2025. It is available to schools outside the UK.
Pearson’s qualification page refers to the modular Mathematics A specification as 4XMA1. The qualification is certificated through Foundation or Higher cash-ins—4XMAF or 4XMAH—and is built from two mandatory unit assessments.
How the modular route is structured
| Tier | Unit 1 | Unit 2 | Cash-in |
|---|---|---|---|
| Foundation | 4WM1F/01 | 4WM2F/01 | 4XMAF |
| Higher | 4WM1H/01 | 4WM2H/01 | 4XMAH |
Each unit is a two-hour written examination worth 100 marks and contributes 50% of the final International GCSE Mathematics A (Modular) qualification. Pearson strongly advises centres to enter Unit 1 before Unit 2 on first entry, although resits can be taken in either order. Both units must ultimately be cashed in for the qualification grade.
Modular Mathematics A versus linear 4MA1
The mathematical curriculum is closely related, but the assessment architecture is different. Linear 4MA1 is taken through its linear paper route. The modular route divides assessment into Unit 1 and Unit 2, allowing the qualification to be built through separate unit examinations before final cash-in.
- Linear route: International GCSE Mathematics A 4MA1.
- Modular route: this page — 4WM1 + 4WM2 units, certificated as 4XMAF/4XMAH.
- Different qualification: International GCSE Mathematics B 4MB1.
- Advanced extension: International GCSE Further Pure Mathematics 4PM1.
What Mathematics is assessed?
Pearson organises the modular content around the same broad mathematical territories used by International GCSE Mathematics A: Number, Algebra, Geometry and Statistics. The key preparation question is therefore not only “Do I know the topic?” but “Which unit and tier am I entered for, and how is that knowledge sampled in the modular assessment?”
Calculator and working
Pearson’s sample assessment materials permit calculators on the modular unit papers and explicitly warn that correct answers without sufficient working may receive no marks. Students should therefore practise visible mathematical method, not calculator-only answer production.
2026–2027 examination availability
Pearson’s current timetables include modular Mathematics A unit papers alongside the linear 4MA1 route. The Summer 2027 final timetable, for example, lists both linear Mathematics A and the modular 4WM unit route. Always use the timetable and information manual for the exact examination series and regional-paper option that applies to your centre.
How to prepare
- Confirm whether the school is entering the linear or modular Mathematics A route.
- Confirm Foundation or Higher tier.
- Identify whether the next assessment is Unit 1 or Unit 2.
- Repair underlying Mathematics through the Mathematics Knowledge Warehouse.
- Use Pearson modular specimen/past materials for paper-specific execution.
- Check current examination dates and rules in Mathematics Examination Tools & Reference.
