Cambridge vs Pearson Edexcel: international exam boards compared
How Cambridge International and Pearson Edexcel compare for IGCSE and A-Level: exam series, grading, modular vs linear structure, and what it means for students.
Most British international schools enter students for exams set by one or both of the two big international boards: Cambridge International (part of Cambridge University Press & Assessment) and Pearson Edexcel. Families often ask which is better. The honest answer is that it depends on the subject and the student.
The key differences
| Cambridge International | Pearson Edexcel International | |
|---|---|---|
| At 16 | Cambridge IGCSE | International GCSE |
| IGCSE grading | A*–G, or 9–1 for many syllabuses | 9–1 |
| At 18 | Cambridge International AS & A Level | International Advanced Level (IAL) |
| A-Level structure | AS can count towards the A-Level, or all exams at the end | Modular units sat across the two years |
| Resits | By component and series | By individual unit |
| Main exam series (A-Level) | June and November (plus March in some regions) | January, June and October |
| Subject range | Very wide, including many languages | Wide, especially in core academic subjects |
Modular vs linear: why it matters
Edexcel IAL is modular. Students sit units throughout Year 12 and Year 13, and can resit individual units to improve their grade. That spreads the pressure and gives early feedback, but means exams in more sessions.
Cambridge A-Level offers a choice. Students can take AS in Year 12 and the rest in Year 13, or sit everything at the end. Resits are by series.
Students who do better with steady, staged assessment often prefer modular routes. Those who prefer time to absorb the whole course before exams may prefer linear.
Subject-by-subject choices
Many schools mix boards. For example:
- Maths: Edexcel IAL Mathematics is popular for its modular structure and flexible combinations.
- Languages: Cambridge offers first-language and foreign-language syllabuses in many world languages.
- Sciences and humanities: both boards are widely used, so schools choose based on specification content and practical requirements.
What parents should ask
- Which board is used for each subject, and why?
- When will exams be sat, and how many sessions are involved?
- What is the school’s resit policy, and does it cost extra?
- If we move, will a new school use the same board for this subject?

Frequently asked questions
Is Cambridge or Edexcel better?
Neither is better overall. Both are long-established, widely recognised boards. Differences in structure and exam timing suit different students and schools, and many schools use both, choosing the board subject by subject.
Do universities prefer one board?
No. UK and international universities accept both boards' IGCSEs and A-Levels equally. They look at the grades and subjects, not the board.
