Edexcel vs CCEA GCSE Maths Grade Boundaries
GCSE maths Edexcel vs CCEA grade boundaries explained for results day, with grading scales, recent thresholds and advice on comparing marks fairly.
Results day can reduce months of work to one anxious question: was my mark enough? Yet a search for GCSE maths Edexcel vs CCEA grade boundaries can create more confusion, because the boards do not use the same grading scale or assessment structure.
The short answer is this: Edexcel reports GCSE Maths on the numbered 999--111 scale and applies one overall raw-mark boundary to three papers. CCEA uses grades A∗A^*A∗--GGG, combines two units through a Uniform Mark Scale (UMS), and includes the additional grade C∗C^*C∗. Their published numbers therefore cannot be compared mark for mark.

Results day comparison checklist
Before interpreting either board's results, check:
- the exam board and specification;
- the tier or CCEA unit combination entered;
- whether the figure is a raw mark or uniform mark;
- the correct examination series;
- the overall subject boundary rather than an isolated paper boundary.
MathsGenie's GCSE grade boundaries hub is a useful starting point, while the dedicated Edexcel GCSE Maths grade boundaries page lets you compare several examination series.
GCSE maths Edexcel vs CCEA grade boundaries
The most important differences appear before any boundary is considered.
| Feature | Pearson Edexcel GCSE Maths | CCEA GCSE Mathematics |
|---|---|---|
| Grading scale | Grades 999--111 | Grades A∗A^*A∗--GGG, including C∗C^*C∗ |
| Structure | Three linear papers in one series | One modular test and one completion test |
| Weighting | Each paper contributes one third | First unit 45%45\%45%; completion test 55%55\%55% |
| Overall scale | Raw marks out of 240240240 | UMS total out of 400400400 |
| Foundation route | Grades 111--555 | M1/M5 or M2/M6, with route-dependent grades |
| Higher route | Grades 444--999, with grade 333 allowed | M3/M7 or M4/M8, with route-dependent grades |
| Boundary use | Overall raw-mark boundaries change by series | Unit raw boundaries change; most subject-level UMS thresholds are fixed |
Edexcel students sit three 808080-mark papers: one non-calculator paper and two calculator papers. The marks are added:
80+80+80=240.80+80+80=240.80+80+80=240.Individual Edexcel papers are not awarded separate qualification grades. Notional paper boundaries may be published for illustration, but the final grade comes from the combined total. Students can prepare through the Edexcel GCSE Maths revision hub and Edexcel past papers with mark schemes.
CCEA is unitised. Students take one unit from M1--M4 and a corresponding completion test from M5--M8. Raw unit marks are converted to UMS so results from different series can be combined fairly. The CCEA GCSE Maths revision hub and CCEA GCSE Maths past papers help students practise the correct route.
Recent Edexcel grade boundaries
For Pearson Edexcel's June 202520252025 series, the confirmed overall boundaries were:
| Tier | Maximum | Grade boundaries |
|---|---|---|
| Higher | 240240240 | 9:2179:2179:217, 8:1868:1868:186, 7:1567:1567:156, 6:1216:1216:121, 5:875:875:87, 4:534:534:53, 3:363:363:36 |
| Foundation | 240240240 | 5:1755:1755:175, 4:1444:1444:144, 3:1053:1053:105, 2:672:672:67, 1:291:291:29 |
These are minimum marks. A Higher mark of 156156156, for example, met the grade 777 boundary in that particular series. It does not predict a future boundary.
The figures also show why percentages from different tiers should not be treated as measures of equal paper difficulty. A grade 444 required 535353 marks on Higher but 144144144 on Foundation because the papers targeted different ranges of mathematical demand.
How CCEA grade boundaries work
CCEA's subject award is reported out of 400400400 UMS. The established subject thresholds for grades AAA--GGG are:
| CCEA grade | Minimum subject UMS |
|---|---|
| AAA | 320320320 |
| BBB | 292292292 |
| C∗C^*C∗ | 268268268 |
| CCC | 240240240 |
| DDD | 200200200 |
| EEE | 160160160 |
| FFF | 120120120 |
| GGG | 808080 |
The A∗A^*A∗ subject boundary is set separately for each examination series. In Summer 202420242024, it was 394394394 UMS. Students should therefore check the official boundary document for their own series rather than assuming that an earlier A∗A^*A∗ threshold still applies.

A CCEA raw mark is not automatically the final figure used for the qualification. The conversion to UMS accounts for differences in unit difficulty between series. That is why placing a CCEA unit raw mark beside an Edexcel total out of 240240240 produces an attractive but misleading comparison.
What the comparison means on GCSE maths results day
Grade boundaries tell you the minimum result needed for a grade in a particular system. They do not prove that one board is easier. The specifications, assessment routes, paper demands and reporting scales differ.
For Edexcel, confirm your combined mark and compare it with the correct tier and series. For CCEA, check the units entered, the UMS awarded and the final subject grade. If a result is unexpectedly close to a boundary, speak to your school or examinations officer about the available post-results options before making assumptions based on a paper score.
Common mistakes when comparing boundaries
Comparing raw marks with UMS
Edexcel's overall total is a raw mark. CCEA converts unit results to UMS. The figures answer different questions.
Translating letters directly into numbers
There is no simple formula that turns every CCEA grade into an Edexcel grade. In particular, CCEA's C∗C^*C∗ grade has no identically named Edexcel counterpart.
Using the wrong examination series
Boundaries belong to a specific series. Previous thresholds are helpful context, not guaranteed targets. During revision, build a safety margin rather than aiming for one historic boundary.
Treating a paper boundary as the final grade
Edexcel's qualification grade uses the combined total. For CCEA, the subject award depends on aggregated UMS from the required units.
Takeaway summary
Edexcel and CCEA boundaries are best understood side by side, not converted into one another. Edexcel uses three papers, 240240240 raw marks and grades 999--111. CCEA uses a unitised structure, 400400400 UMS and grades A∗A^*A∗--GGG with C∗C^*C∗.
The calmer approach is also the more useful one: identify your board, route and series first, then read the correct boundary table. For future exams, begin with MathsGenie's GCSE Maths revision hub, use Edexcel mini tests for focused practice, and move on to predicted GCSE Maths papers. Revision lessons build the method; practice questions, past papers, mark schemes and video solutions turn that method into dependable marks.
