Navigating results day with a mix of letters and numbers can raise many questions for parents. This comprehensive guide to the igcse grading system breaks down everything Sharjah families need to know—explaining how the A*–G and 9–1 scales work, what grade boundaries and percentages mean, and how these results shape subject choices and university pathways.
How Does the IGCSE Grading System Work?
The IGCSE grading system can look different depending on the awarding body and syllabus. At Scholars International Academy (SIA), learners in Years 10 and 11 follow Cambridge International IGCSE courses. Cambridge IGCSEs are generally graded from A* to G, although Cambridge also offers 9 to 1 versions of selected syllabuses in settings where that grading option is available.
Pearson Edexcel International GCSEs use the 9 to 1 scale, with 9 as the highest grade and 1 as the lowest graded outcome. That is why families comparing schools or qualifications may see letters on one results sheet and numbers on another.
The scales report attainment differently, so they are not a perfect one-to-one conversion. If you are comparing the qualifications themselves, our guide to the difference between IGCSE and GCSE explains the wider differences.
What Each IGCSE Grade Means
With IGCSE grades explained clearly, results are easier to interpret. First, check which grading scale applies to the subject.
1. The A* to G Scale
On the Cambridge A* to G scale, A* is the highest grade, followed by A, B, C, D, E, F, and G. A result of U means the performance did not reach the minimum standard for a graded result.
A* indicates very high achievement, while A and B also represent strong performance. C is commonly used by schools and sixth-form providers as an important progression benchmark, but it is not a universal pass mark for every subject or institution.
Grades below C are still classified results, but whether they meet a progression requirement depends on the institution.
2. The 9 to 1 Scale
The IGCSE 9-1 grading scale runs from 9, the highest grade, to 1, with U for ungraded. Pearson Edexcel International GCSEs use this scale.
The system gives more differentiation at the top end. Grade 7 broadly aligns with the old A benchmark, while grade 4 broadly aligns with the old C benchmark. Grades 8 and 9 sit above that level, with grade 9 intended for the highest-performing students.
For parents searching for the IGCSE 9 to 1 grading scale UAE, it is better to think in broad bands than force an exact conversion. Grades 9 to 7 represent high attainment, 6 to 4 sit around the middle range, and 3 to 1 are lower graded outcomes. The IGCSE grading system should still be read alongside the requirements of the next school or study pathway.
IGCSE Grading System Percentage: How Marks Become Grades
A common mistake is assuming that a fixed percentage always equals a particular grade. It does not.
The IGCSE grading system percentage works through grade thresholds rather than a permanent percentage chart. After marking, the awarding body sets the minimum mark needed for each grade. Thresholds can move because papers vary in difficulty between sessions.
The mark needed for an A, A*, 7, or 9 can therefore vary by subject and session. Be cautious with generic charts claiming that a percentage always guarantees a particular grade. Check the official threshold table for the exact syllabus and session to understand the IGCSE grading system accurately.
IGCSE Pass Mark and What Counts as a Good Score
There is no single IGCSE pass mark that applies to every school, subject, university, or progression route.
In practice, C on the A* to G scale and 4 on the 9 to 1 scale are often used as important benchmark grades. However, a school may require a B, A, 6, 7, or higher to continue with a subject at A-Level, particularly in Mathematics, Sciences, or other demanding courses.
So, what is a good IGCSE score for university? There is no universal number. Universities normally consider later qualifications, such as A-Levels, alongside the wider academic record, although strong IGCSE grades can still matter for competitive courses or specific subject requirements.
A useful way to read a grade profile is:
- Sixth-form progression: check the minimum grade for each intended A-Level subject
- Strong academic profile: look for consistently high grades across core and chosen subjects
- Competitive pathways: focus on subjects connected to the degree the student may later pursue
Subject choice matters too. SIA’s guide to choosing IGCSE subjects can help families understand how options may support later study.
Difference Between A* and Grade 9 in IGCSE
The difference between a star and grade 9 IGCSE results is easy to oversimplify.
A* is the highest grade on the traditional A* to G scale. Grade 9 is the highest grade on the 9 to 1 scale and was introduced to identify achievement at the very top of the performance range. In Pearson’s comparison, grade 9 represents a higher level of attainment than the old A* benchmark.
That does not mean every A* can simply be converted into a 9. The grades come from different grading structures and should be interpreted within the exam board and syllabus used. This is one of the areas where the IGCSE grading system is often misunderstood.
IGCSE Results Day: What to Expect
IGCSE results day is when students receive the final grades awarded for each subject. The exact date depends on the exam board and exam series.
For Cambridge, June-series IGCSE results are normally released in August, while November-series results are released in January. Schools tell families how and when individual results can be accessed, and certificates follow later.
If a result is unexpected, the school can explain the available post-results options, which may include an enquiry about results or a future resit where appropriate. Families can also review SIA’s published examination results to understand the school’s wider academic performance.
Conclusion
Understanding the IGCSE grading system is less about memorising a conversion chart and more about knowing which exam board and syllabus your child is taking, how grade thresholds are set, and what grades are needed for the next step.
An A* and a 9 are top outcomes on their respective scales, but should not automatically be treated as identical. Percentages are raw marks until the relevant grade thresholds are applied.
For parents reviewing results, the IGCSE grading system is most useful when viewed as a complete profile: does it support the subjects and pathway the student wants to pursue next?
