Quick answer: IGCSE vs GCSE, what is the difference and which should your child take? The IGCSE is the international version of the GCSE, sat at 16 after Years 10 and 11. GCSEs in England use 9 to 1 grades; IGCSEs use 9 to 1 or A* to G depending on the syllabus. Both lead to A Levels or the IB, and in Barcelona The British College of GavĂ teaches Pearson Edexcel IGCSEs.

Key takeaways
- GCSEs in England have been graded 9 to 1 since 2017; the bottom of a 7 is comparable to the bottom of an old A, and the bottom of a 4 to the bottom of an old C (Ofqual).
- Cambridge IGCSE offers more than 70 subjects, with some syllabuses graded A* to G and others 9 to 1 (Cambridge International).
- Pearson Edexcel International GCSEs are offered in May-June and November, with entry options that vary by subject, and many offer a choice of linear or modular assessment (Pearson).
- At The British School of Barcelona, Year 10 and 11 tuition at the Sitges and Castelldefels campuses is 17,250 euros in 2026-27, with external exam fees charged separately (school fee page).
At British schools in Barcelona, option choices for the two-year course that ends in exams at 16 usually start in Year 8 or Year 9. That is also when parents meet the alphabet soup of IGCSE vs GCSE, International GCSE and "9 to 1", often on the same school website.
The good news is that the differences are smaller than the names suggest. This guide explains what separates the two qualifications, how the grades compare, which one schools in Barcelona use and what Years 10 and 11 cost in 2026-27.
What is the difference between IGCSE and GCSE?
A GCSE is the qualification taken by 16-year-olds in England, while an IGCSE (or International GCSE) is the version exam boards design for schools outside the UK. Cambridge says it aligns the standard of its IGCSE with the GCSE taken in England, so the level of difficulty is meant to be the same. What changes is the content, the grading options and how flexible the exams are.
| Feature | GCSE (England) | IGCSE / International GCSE |
|---|---|---|
| Designed for | Schools in England | International schools |
| Grading | 9 to 1 since 2017 | 9 to 1 or A* to G, by syllabus |
| Exam sessions | Summer; November resits in English and maths only | May-June and November for many subjects (Pearson) |
| Assessment | Mainly exams at the end of two years | Exams plus oral, coursework or practical in some subjects |
| Typical course | Two years, all exams at the end | Two years, Years 10 and 11 |

How do IGCSE and GCSE grades compare?
On the 9 to 1 scale a 9 is the top grade and U means ungraded. Ofqual says the numbers are not directly equivalent to the old letters, but they line up at three points:
- Grade 7: the bottom of a 7 matches the bottom of an old A.
- Grade 4: the bottom of a 4 matches the bottom of an old C.
- Grade 1: the bottom of a 1 matches the bottom of an old G.
Cambridge IGCSE still offers both scales: Biology, for example, exists as syllabus 0610, graded A* to G, and as 0970, graded 9 to 1. Worked example: if a sixth form asks for a 7 in Maths and your child sat an A* to G syllabus, an A is the comparable grade and a C is comparable to a 4; ask the sixth form how it reads letter grades. Wales and Northern Ireland use different GCSE scales, which matters if you are moving from there.
IGCSE or GCSE, which is better for your child?
Neither is better in itself: universities and sixth forms read them as the same level, so the subjects and grades your child achieves matter far more than the label. The real choice is usually made by the school, which picks a board and syllabus for each subject.
For families abroad, the international versions have practical advantages. Pearson designs its International GCSEs for international learners and runs many of them in two sessions a year, May-June and November, which gives more room to resit. The English GCSE, by contrast, only allows November resits in English language and maths.
One tip for Barcelona: schools use the names loosely. The British School of Barcelona calls its Year 11 exams GCSEs, while St. George Barcelona uses both GCSE and IGCSE on different pages of its website and lists IGCSE exams among its extra fees. Ask for the board and syllabus code of each subject, which tells you exactly what your child will sit.
What Spanish families in Barcelona should check
A British pathway does not automatically give a Spanish secondary certificate. To obtain the Graduado en ESO, families apply to the Ministry of Education for homologation, and the ministry confirms this step is needed for both the ESO and Bachiller titles. The ministry also confirms that an equivalence scheme exists for British secondary qualifications, so ask the school which documents recent leavers needed.
Some schools plan for this. The British School of Barcelona says its secondary curriculum lets students complete the Spanish ESO qualification by the end of Year 11, and The British College of GavĂ requires students of Spanish nationality to take Catalan alongside their IGCSEs. If your child might switch to the Spanish Bachillerato at 16, raise it with the school before Year 10 options are fixed.
British schools in Barcelona and their IGCSE routes
The British School of Barcelona
BSB students usually take 9 or 10 subjects at the end of Year 11, depending on whether they study the three sciences separately or as Co-ordinated Science, which counts as two grades. Most sit Spanish early, in Year 10, and the top Maths set also sits Maths in Year 10 before Further Maths. After Year 11 students choose between the IB Diploma and A Levels at the Nexus sixth form building.
St. George Barcelona
St. George prepares Key Stage 4 students for exams on the 9 to 1 scale, with core subjects plus options in business, arts, humanities or technology. The school reports that 96% of its students achieved grade 4 or above. From Year 12 it offers the IB Diploma; our article on St. George Barcelona's 2026 IBDP and IGCSE results has the latest figures.
The British College of GavĂ
BCG, in GavĂ in the Baix Llobregat area, teaches Pearson Edexcel IGCSEs in Years 10 and 11. Core subjects are English, Maths, Science (co-ordinated or separate), Spanish, Catalan, PE and PSHE, with options such as Economics, Computer Science and Psychology chosen in Year 9. The school says its IGCSEs prepare students for A Levels, the Spanish Bachillerato or the IB Diploma and Career-related Programmes.

- A one-off matriculation fee, 3,400 euros at every BSB campus.
- External exam entry fees, charged separately at BSB and St. George.
- Uniform, lockers, trips and school transport, all extra at BSB.
Questions to ask before Year 10 options
- Which board and syllabus code applies to each subject, and is it graded 9 to 1 or A* to G?
- How many subjects will your child sit, and can any be taken early, as BSB does with Spanish?
- What grades does the sixth form require for the A Level or IB subjects your child is considering?
- How are resits handled if a grade falls short, and in which session?
- Does the timetable cover ESO homologation and Catalan if your child may stay in the Spanish system?

Frequently asked questions
Are IGCSE and GCSE the same?
They are the same level but not identical. Cambridge aligns the standard of its IGCSE with the GCSE taken in England, while Pearson designs its International GCSEs for students outside the UK. Content and exam options differ: many International GCSEs can be sat in May-June or November, whereas English GCSE resits are limited to November in English language and maths.
How do IGCSE grades convert to GCSE grades?
Use the anchor points set out by Ofqual. The bottom of a grade 7 is comparable to the bottom of an old A, the bottom of a 4 to the bottom of a C, and the bottom of a 1 to the bottom of a G. Some Cambridge IGCSE syllabuses still award A* to G, so for a requirement of a 7 the comparable letter grade is an A.
Do British schools in Barcelona teach IGCSE or GCSE?
Both names appear. The British College of GavĂ teaches Pearson Edexcel IGCSEs, The British School of Barcelona calls its Year 11 exams GCSEs, and St. George Barcelona uses both terms on its website and lists IGCSE exam fees among its extras. Ask each school for the board and syllabus code of every subject your child will sit.
