Cambridge 9709 vs Edexcel IAL Mathematics: AS and A Level comparison
Updated for current teaching sessions. Cambridge facts follow syllabus 9709 for 2028–2030. Edexcel facts follow the International Advanced Level Mathematics modular specification (unit codes such as WMA11). Confirm your centre’s entry combination.
Cambridge International AS & A Level Mathematics (9709) and Pearson Edexcel International Advanced Level Mathematics (IAL) both develop Pure Mathematics with optional Mechanics and Statistics pathways. Universities recognise both families widely. That does not make them the same exam.
The critical difference for students is structure: Cambridge builds AS/A Level around a fixed set of components (Papers 1–6 with allowed routes). Edexcel IAL is modular — separate units such as WMA11–WMA14, WME01, and WST01, each assessed in its own paper. Topic overlap is real; paper interchangeability is not.

AS vs A2: which papers / units you sit
Parents and students usually ask this first. Below, “AS” means the first half (Cambridge AS Level / Edexcel IAS). “A2” means the second-year papers or units you add to complete the full A Level. Confirm the exact combination with your school — centres choose allowed routes.
Side-by-side: AS stage
| AS stage | Cambridge 9709 (pick one allowed route) | Edexcel IAS Mathematics |
|---|---|---|
| How many? | 2 papers in the same series | 3 units |
| Compulsory Pure | Always includes Paper 1 (P1) | Always includes P1 (WMA11) and P2 (WMA12) |
| Common route A | Paper 1 + Paper 4 (Mechanics) | P1 + P2 + M1 (WME01) |
| Common route B | Paper 1 + Paper 5 (S1) | P1 + P2 + S1 (WST01) |
| Other option | Paper 1 + Paper 2 (Pure only) — AS only; cannot later count toward A Level | P1 + P2 + D1 (Decision) if the centre offers it |
| What you do not sit yet | Paper 3 (P3) and the second applied paper for full A Level | P3 (WMA13), P4 (WMA14), and the second applications unit |
Side-by-side: A2 stage (to complete full A Level)
| A2 / full A Level completion | Cambridge 9709 | Edexcel IAL Mathematics |
|---|---|---|
| Total exams for full award | 4 papers in total (AS + A2, or all linear) | 6 units in total (IAS + A2 units) |
| Compulsory Pure added / required | Paper 1 + Paper 3 are required for A Level (P3 is the main A2 Pure paper) | P1, P2, P3, P4 all compulsory for IAL Mathematics |
| Typical A2 Pure | Paper 3 (P3) | P3 (WMA13) and P4 (WMA14) |
| Applied pair option 1 | Paper 4 (Mechanics) + Paper 5 (S1) | M1 + S1, or M1 + D1, or M1 + M2, or S1 + D1, or S1 + S2 |
| Applied pair option 2 | Paper 5 (S1) + Paper 6 (S2) | Same list — centre chooses two allowed applications units |
| Not allowed | Paper 4 with Paper 6 together | Re-using the same unit result for two different cash-in awards |
| If you already sat AS | Add the two remaining A Level components in a later series (staged route) | Add the three remaining units (usually P3, P4 + second applications unit) |
Worked examples (common school paths)
- Cambridge AS → A2 (Mechanics + Statistics path): Year 1 AS = Paper 1 + Paper 4. Year 2 A2 = Paper 3 + Paper 5. Full A Level set = Papers 1, 3, 4, 5.
- Cambridge AS → A2 (Statistics path): Year 1 AS = Paper 1 + Paper 5. Year 2 A2 = Paper 3 + Paper 6. Full A Level set = Papers 1, 3, 5, 6.
- Cambridge linear A Level: sit Papers 1, 3, 4, 5 (or 1, 3, 5, 6) in the same series — still four papers total.
- Edexcel IAS → IAL (Mechanics then Statistics): Year 1 IAS = WMA11 + WMA12 + WME01. Year 2 A2 = WMA13 + WMA14 + WST01. Full IAL = six units.
- Edexcel IAS → IAL (Statistics then further Statistics): Year 1 = WMA11 + WMA12 + WST01. Year 2 = WMA13 + WMA14 + WST02 (if entered for S1+S2).
Cambridge 9709 — every component listed
Use this list with the AS/A2 tables above. Paper 2 is only for the AS Pure-only route and does not progress into A Level.
| 9709 paper | Focus | Usually sits at | Typical length / marks |
|---|---|---|---|
| Paper 1 (P1) | Pure Mathematics 1 | AS and A Level (compulsory) | 1 h 50 min · 75 marks |
| Paper 2 (P2) | Pure Mathematics 2 | AS Pure-only route (no A Level carry-forward) | 1 h 15 min · 50 marks |
| Paper 3 (P3) | Pure Mathematics 3 | A Level / A2 Pure | 1 h 50 min · 75 marks |
| Paper 4 (M1) | Mechanics | AS option or A Level applied pair | 1 h 15 min · 50 marks |
| Paper 5 (S1) | Probability & Statistics 1 | AS option or A Level applied pair | 1 h 15 min · 50 marks |

Edexcel IAL — every common Mathematics unit listed
IAS Mathematics = three units (P1, P2 + one of M1 / S1 / D1). Full IAL Mathematics = six units (P1–P4 + two allowed applications units). Each unit is typically 1 hour 30 minutes and 75 marks.
| Unit | Code | Usually sits at | Content focus (overview) |
|---|---|---|---|
| Pure Mathematics 1 | WMA11 | IAS and IAL (compulsory) | Algebra & functions; coordinate geometry; trigonometry; differentiation; integration |
| Pure Mathematics 2 | WMA12 | IAS and IAL (compulsory) | Proof; further algebra; sequences; exponentials & logs; calculus |
| Pure Mathematics 3 | WMA13 | A2 / IAL Pure (compulsory for full IAL) | Further algebra & calculus; numerical methods |
| Pure Mathematics 4 | WMA14 | A2 / IAL Pure (compulsory for full IAL) | Further Pure including vectors and binomial work |
| Mechanics 1 | WME01 | IAS option or IAL applications pair | Mechanics applications |
| Statistics 1 | WST01 | IAS option or IAL applications pair | Statistics applications |
| Mechanics 2 / Statistics 2 / Decision 1 | WME02 / WST02 / WDM11 | IAL second applications unit (if chosen) | Only if your cash-in combination requires it |
Where students go wrong
| Mistake | Why it hurts | Guided fix |
|---|---|---|
| Treating P1 as WMA11 | Similar Pure topics; different paper design and mark schemes | Use the hub that matches your entered code |
| Ignoring route rules in 9709 | Wrong paper pairs cannot cash into the intended AS/A Level | Confirm AS vs A Level combination with school before buying books |
| Mixing Mechanics papers across boards | M1 label is not universal | 9709 Paper 4 ≠ WME01 as an exam rehearsal set |
| Late board switch without rebuild | Muscle memory from the other board leaks into timing | Rebuild with 4–6 weeks of board-specific timed papers |
How I guide the choice in consultation
- First question: which board is your school already entered for? Follow that unless the centre is changing policy.
- Second: do you need a modular calendar (IAL unit retakes / staged sittings) or a Cambridge component route your teachers already teach?
- Third: Mechanics vs Statistics preference at AS — both boards offer paths, but the paper codes and later combinations differ.
- Never choose by “which past paper PDF looks easier online”. Choose by entry, teaching support, and university advice for your country.
Topic comparison by paper / unit
This is an orientation map of syllabus themes. Matching topic names (for example Differentiation or Normal distribution) does not mean the papers are interchangeable. Use it to understand vocabulary — then revise the entered code only.
Pure Mathematics topics

How to revise from this topic map
- Highlight only the papers/units on your statement of entry.
- Make a topic checklist from that column alone (9709 paper list or IAL unit list).
- Do not fill gaps with the other board’s past paper just because the topic title matches.
- After topical drills, sit a full entered paper/unit under time and mark with its scheme.
Rough paper-to-unit map (orientation only)
Quick vocabulary bridge after the topic tables. Still not a claim of equivalence.
| Theme | Cambridge 9709 example | Edexcel IAL example |
|---|---|---|
| Early Pure | Paper 1 (P1) | WMA11 |
| Further Pure at AS/A | Paper 2 / Paper 3 | WMA12 / WMA13 / WMA14 |
| Mechanics | Paper 4 | WME01 (+ further M units if entered) |
| Statistics | Paper 5 / Paper 6 | WST01 (+ further S units if entered) |
Revision playbooks
- 9709: lock the exact paper list for your AS or A Level route, then rotate Pure and applied papers weekly.
- IAL: lock unit codes on the entry, sit unit-length timed papers (often 1 h 30), and track each unit’s weak topics separately.
- Both: mark with the matching mark scheme; keep an error log (algebra, proof, modelling, data).
- Both: in the final month, full papers beat random textbook chapter hopping.

Common questions
Which board is “better” for universities?
Both Cambridge International AS & A Level and Pearson Edexcel IAL are widely recognised. Local university conditional offers and your school’s teaching strength matter more than online brand preference.
Can I practise Cambridge papers for Edexcel Pure?
Use them only for shared method practice early on. Exam rehearsal must be on your entered unit papers and mark schemes.
I am doing 9709 Paper 1 and Paper 2. Can I carry that to A Level?
The Pure-only AS route (Paper 1 and Paper 2) is AS Level only and cannot later count toward A Level Mathematics. Confirm your planned combination before you commit a year of revision.
