Cambridge IGCSE results are graded on a scale from A* (highest) to G (lowest), based on a student’s Uniform Mark achieved in each subject. An A* reflects a mark of 90–100%, while a G reflects 20–29%. Grades are issued per subject, not as an overall aggregate and are recognised by universities and employers in more than 160 countries.
Parents researching IGCSE schools in Singapore should look beyond the grade letters themselves and understand how those grades are calculated, what they signal about a child’s readiness for further study and how a school’s track record of results reflects its teaching quality.
This guide breaks down exactly what Cambridge IGCSE grades mean, how the grading system works and what GIIS Singapore’s own results tell parents about the strength of its Cambridge programme.
Key takeaways to understanding IGCSE scoring system:
- IGCSE Curriculum helps you evaluate a school’s academic outcomes accurately. A school claiming “excellent results” should be able to show you what percentage of students achieved A* and A grades — not just anecdotal success stories.
- IGCSE helps progression to IB Diploma, A-Levels, or other pre-university pathways, where minimum grade requirements are common.
What Is the Cambridge IGCSE?
The Cambridge International General Certificate of Secondary Education (IGCSE) is an English-medium secondary school qualification developed by Cambridge Assessment International Education (CAIE), a department of the University of Cambridge. It is comparable to the UK’s GCSE and is typically taken by students aged 14 to 16, corresponding to Grades 9 and 10.
The IGCSE sits within Cambridge’s broader four-stage education pathway:
| Cambridge Stage | Typical Age |
| Cambridge Primary | 5+ |
| Cambridge Lower Secondary (CLSP) | 11+ |
| Cambridge Upper Secondary (IGCSE) | 14+ |
| Cambridge Advanced (A Level) | 16+ |
At GIIS Singapore, Cambridge education begins with the Cambridge Lower Secondary Programme (CLSP) in Grades 6–8, which builds naturally into IGCSE for Grades 9 and 10. This progression gives students a two-stage runway rather than a sudden jump into an unfamiliar assessment style at age 14.
The programme is a two-year course. It is designed to build critical thinking, adaptability and strong English-language communication skills — competencies that matter as much for university interviews and workplace readiness as they do for exams.
How Does The Cambridge IGCSE Grading System Work?
The A* to G Scale
Cambridge IGCSE results are reported using eight grade bands, from A* (the highest) to G (the lowest passing grade). Each subject a student takes is graded independently — there is no single combined score across all subjects, unlike some national board systems.
| 等级 | Percentage (Uniform) Mark Range |
| A* | 90–100 |
| A | 80–89 |
| B | 70–79 |
| C | 60–69 |
| D | 50–59 |
| E | 40–49 |
| F | 30–39 |
| G | 20–29 |
How does this work:
- Cambridge does not simply add up raw exam marks and apply this table directly.
- Because papers and question difficulty can vary slightly from one exam series to another, Cambridge converts a student’s raw mark into a Uniform Mark, using a process called grade boundary setting.
- This ensures a “B” grade represents the same standard of achievement whether a student sat the exam in May or October, or in a year when the paper was marginally harder or easier.
- This is why Cambridge describes its grading as using “a mix of statistical and judgemental evidence” — statisticians review mark distributions and senior examiners review actual scripts, before final grade boundaries are confirmed.
How Many Subjects Do Students Take in IGCSE?
Cambridge IGCSE offers more than 70 subjects, including 30 languages, which schools combine to suit their students. Most students choose somewhere between 5 and 14 subjects, with English, Mathematics and Science treated as core.
At GIIS Singapore, subjects are structured across five groups:
- Languages — English, English as a Second Language, French, Hindi, Tamil GCE ‘O’ Level, Mandarin
- Humanities & Social Sciences — Economics, Literature in English, Global Perspectives, Environmental Management
- Sciences — Physics, Chemistry, Biology, Environmental Management
- Mathematics — Mathematics, Additional Mathematics (Grade 10)
- Creative, Technical & Vocational — Business Studies, Computer Science, Design & Technology, Global Perspectives
This breadth is deliberate. It allows a student who wants to specialise in the sciences ahead of an IB Diploma or A-Level pathway to do so, while a student with strengths in business or the humanities can weigh their subject choices accordingly.
How Cambridge IGCSE Results Are Assessed
Unlike a single year-end exam, Cambridge IGCSE assessment at GIIS draws on a structured sequence of internal and external evaluations throughout the two-year programme:
- Two Cyclic Tests (CTs)
- Semester 1 examinations
- Pre-board examinations
- Semester 2 examinations
- A third Cyclic Test
Cambridge examinations run in three global series — February (India only), May/June and October/November — with results released in May, August and January respectively.
What Do Your Child’s IGCSE Results Actually Mean?
For University and Further Study
Cambridge IGCSE is recognised by universities, education systems and employers worldwide. It is widely accepted as an entry qualification into pre-university pathways such as the IB Diploma Programme or A-Levels.
For Subject Progression
Because grading is subject-specific, results also help identify where a student’s strengths genuinely lie — information that is directly useful when choosing IB Diploma subjects, A-Level subjects, or a pre-university specialisation two years later.
GIIS Singapore’s Cambridge IGCSE Track Record
Transparency is central to how GIIS communicates academic outcomes to parents. Over the past three years, GIIS Singapore has recorded consistently strong IGCSE performance:
| Year | Overall A* and A | ICE Distinction / Merit |
| 2022 | 84% | 100% |
| 2023 | 80.2% | 100% |
| 2024 | 84% | 100% |
The school has recorded 100% ICE Distinction in Grade 10 results across recent years, with more than 85% of students consistently scoring A* in individual subjects during recent final examinations.
In the 2023 IGCSE cohort specifically, GIIS Singapore results included:
- 100% of students achieved the ICE Distinction
- 13 students attained A* grades across every subject they attempted
- 12 students secured 9 A* grades
- Of 128 students, more than 80% achieved A* and A grades, with over 10% attaining perfect scores
These outcomes are not incidental. They reflect a deliberate combination of structured multi-stage assessment (Cyclic Tests, semester exams and pre-boards), the CLSP-to-IGCSE progression that builds readiness before Grade 9 and a faculty focused specifically on Cambridge pedagogy.
Final Thoughts: Why GIIS Singapore’s Approach Supports Strong IGCSE Results
A Structured Two-Stage Cambridge Pathway
Students don’t arrive at IGCSE unprepared. The Cambridge Lower Secondary Programme in Grades 6–8 introduces the academic habits, English-language rigour and inquiry-based learning style that Cambridge assessment expects, so the transition into IGCSE in Grade 9 is a continuation rather than a disruption.
Data-Driven Progress Tracking
GIIS Singapore uses granular tracking that allows teachers to identify a student’s specific strengths and gaps well before final examinations, rather than relying on end-of-year surprises.
Holistic Development Alongside Academics
Academic rigour at GIIS runs alongside the school’s 9GEMS holistic education framework, along with structured co-curricular and extra-curricular programmes.
Experienced Cambridge Faculty
GIIS Singapore’s Cambridge programme is delivered by faculty trained specifically in Cambridge assessment methodology, within a curriculum researched under Cambridge guidelines and adapted to student needs at the SMART Campus.

常见问题
What is the highest grade in Cambridge IGCSE?
A* is the highest grade, awarded for a Uniform Mark of 90–100%.
Is a C grade a pass in IGCSE?
Yes. Grades A* through G are all considered passing grades under the Cambridge system, though universities and pre-university programmes often set minimum grade requirements — commonly around a B or C in core subjects — for progression.
How many subjects does a student need to take for IGCSE?
Students typically take between 5 and 14 subjects, with English, Mathematics and Science forming the core. At GIIS Singapore, Grade 9 and Grade 10 students follow a structured subject list spanning languages, humanities, sciences, mathematics and technical/creative options.
Does the Cambridge IGCSE grading scale differ between schools?
No. Grade boundaries and the A*–G scales are set by Cambridge Assessment International Education globally, not by individual schools. What differs between schools is the quality of preparation and teaching that determines how many students reach the top of that scale.
How does IGCSE prepare students for the IB Diploma?
IGCSE’s subject-specific grading and broad curriculum give students a clear picture of their academic strengths, which directly informs IB Diploma subject selection two years later. The rigour of IGCSE’s assessment style — combining coursework, written papers and orals — also mirrors the sustained-effort structure the IB Diploma requires.
