The British education system revolves not around grades, but around exams. Each critical exam determines which school a child enters, what curriculum they follow, and which universities they can apply to. For Chinese parents, the terminology alone is confusing: 11+, Common Entrance, GCSE, IGCSE, A-Level, Sixth Form—each points to a different age, school type, and pathway.
This article uses Eton College, the most famous of Britain's historic public schools, as a case study to break down four critical exams in British education: what they test, why they matter, and how they map to China and Singapore international schools. Whether your child attends a British-system school in Singapore like TTS or Dulwich, or you're planning for UK boarding school, understanding these exams is the first step in making the right educational decisions.
British Grade Naming
Before diving into the exam system, it helps to understand how Britain names its grades. Britain does not use China's Grade 1/Grade 2 or America's Grade 1/Grade 2. Instead, it uses a unique Year system grouped into Key Stages:
- •Nursery (age 3-4) & Reception (age 4-5): Early Years Foundation Stage (EYFS)
- •Year 1 to Year 2 (age 5-7): Key Stage 1 (KS1)
- •Year 3 to Year 6 (age 7-11): Key Stage 2 (KS2), primary school
- •Year 7 to Year 9 (age 11-14): Key Stage 3 (KS3), lower secondary
- •Year 10 to Year 11 (age 14-16): Key Stage 4 (KS4), GCSE/IGCSE stage
- •Year 12 to Year 13 (age 16-18): Key Stage 5 (KS5), also called Sixth Form, A-Level stage
Note that the Year system is named one year ahead of the American Grade system: British Year 2 equals American (and UWC/SAS) Grade 1. This is because Britain counts Reception (age 4-5) as the first formal school year, while the American system starts with Kindergarten (age 5-6) and Grade 1 from age 6.
Another commonly confusing concept is Key Stage. Key Stages are not grade names but curriculum and assessment groupings. Each Key Stage ends with a corresponding assessment or exam: KS2 ends with SATs, KS4 ends with GCSE, and KS5 ends with A-Level.
The table below maps every British grade to Singapore international schools, with exam transition points highlighted.

11+ Exam
The 11+ is the first major selective exam in the British system, named after the age of the candidates (10-11). Children sit the exam in their final year of primary school (Year 6) and, if successful, enter Year 7—the first year of secondary school. The 11+ is not a national standardised test; the content, format, and difficulty vary by school and region.
The 11+ serves two main purposes. First, entry to Grammar Schools—selective state-funded secondary schools that are free but intensely competitive, typically 450 applicants for 80 places. Second, entry to Independent Schools—top private schools also select at this age, but usually use their own entrance papers rather than the standardised 11+ format.
Exam subjects typically include four areas: English (reading comprehension, writing), Mathematics, Verbal Reasoning, and Non-Verbal Reasoning. Verbal and Non-Verbal Reasoning are not taught as regular school subjects and require specific preparation. Grammar school exams are usually multiple-choice, set by GL Assessment or CEM; private schools tend to use their own written papers.
13+ / Common Entrance
If the 11+ is the first door to British secondary school, the 13+/Common Entrance is the ticket to Britain's most elite private schools. This exam is sat at the end of Year 8 (age 13), with successful candidates entering Year 9. Britain's most famous public schools—Eton, Harrow, Winchester, Westminster—traditionally admit at 13, not 11.
Common Entrance (CE) is set by the ISEB (Independent Schools Examination Board) and covers eight subjects: English, Mathematics, Science, French (or another modern language), Latin (or a classical language), History, Geography, and Religious Studies. The exam is taken at the student's current school, but papers are marked by the target school to its own standard. This means the same paper has very different "pass marks" depending on the school—elite schools set far higher thresholds.
Using Eton as an example: boys register before the end of Year 5 (age 10). In Year 6 (age 11) they attend an Assessment at Eton and, if successful, receive a Conditional Place. In Year 7 they meet House Masters and choose a boarding house. Finally in Year 8 (age 13) they sit Common Entrance, Eton Entrance, or the King's Scholarship exam; upon meeting the standard they formally enter Year 9. Eton labels its five year-groups as Blocks: F Block (Y9) → E Block (Y10) → D Block (Y11) → C Block (Y12) → B Block (Y13).
Notably, Eton also offers a small number of Sixth Form (16+) entry places each year (around 10-15), requiring at least six GCSEs at Grade 7 or above—extremely competitive.
To be clear, Blocks are simply Eton's internal naming for year groups—they do not represent separate entry points. Eton has only two entry points: Year 9 (F Block, via 13+/Common Entrance) and Year 12 (C Block, Sixth Form entry, approximately 10-15 places per year). Once admitted at Year 9, students progress automatically from F Block through to B Block with no additional entrance exams in between.
GCSE / IGCSE
GCSE (General Certificate of Secondary Education) is one of the most important exams in the British system, studied during Years 10-11 (age 14-16) and examined at the end of Year 11. GCSE can be thought of as the British equivalent of China's zhongkao, but its influence extends further—GCSE results not only determine whether a student can progress to Sixth Form for A-Levels, but also appear on university applications.
Students typically study 9-12 subjects. Core subjects include English (Language + Literature, two separate GCSEs), Mathematics, and Science (either combined or separate Physics/Chemistry/Biology). Students also choose electives from humanities, languages, arts, and technology.
The GCSE grading system was reformed in 2017, changing from the traditional A*-G letter grades to a 9-1 numerical scale. 9 is the highest, 4 is a "standard pass," and 5 is a "strong pass." Most Sixth Forms require at least Grade 4 in English and Maths to proceed to A-Level. Elite schools (like Eton's Sixth Form entry) require at least six Grade 7s.
IGCSE (International GCSE) is the international version, set by Cambridge Assessment International Education (CAIE) and others, designed for international schools outside the UK and some UK private schools. IGCSE still uses the A*-G letter grading. IGCSE and GCSE are considered academically equivalent, though exam formats differ slightly—IGCSE relies more on final exams while GCSE may include more coursework.
In Singapore, the following international schools use IGCSE: TTS (Year 10-11, 2-year IGCSE), Dulwich College Singapore (Year 9-11, unique 3-year programme—the only school in Singapore with a 3-year IGCSE), Nexus International School (Year 10-11), and SJI International (Grade 9-10, with Foundation IGCSE in Grades 7-8). Schools that do NOT use IGCSE: UWCSEA (own curriculum + IBDP), NLCS Singapore (pure IB: MYP + IBDP), Singapore American School/SAS (US curriculum + AP).
A-Level
A-Level (Advanced Level) is the final academic exam in the British system, completed during Sixth Form (Years 12-13, age 16-18). If GCSE is the "zhongkao," then A-Level is Britain's "gaokao"—it directly determines which university a student can enter.
Unlike GCSE's 9-12 subjects, A-Level involves deep study of only 3-4 subjects. This "fewer subjects, greater depth" model is fundamentally different from China's gaokao, and closer to university-level specialisation. Students choose their A-Level subjects at the end of Year 11, and the choice is critical—UK university admissions look directly at A-Level subjects and grades.
A-Level is graded A*, A, B, C, D, E—where A* is the highest and E is the lowest passing grade. Oxford and Cambridge typically require A*A*A or A*AA. Most Russell Group universities (the UK's top research university alliance) require AAB to A*AA.
What is Sixth Form? Sixth Form is the collective name for Years 12 and 13, historically the "sixth form" of secondary school. Students can attend Sixth Form at their existing school (like TTS's Sixth Form), at a standalone Sixth Form College, or at a Further Education College. Entry typically requires GCSE results meeting a minimum standard (usually at least five Grade 4s or above).
A-Level vs IB: In Singapore, TTS is the only international school offering both A-Level and IB Diploma pathways. Other British-system schools (Dulwich, Nexus) transition from IGCSE to IB Diploma rather than A-Level. A-Level suits students with a clear academic direction (deep study of 3-4 subjects); IB suits students wanting breadth (6 subjects + core components). Both are recognised globally by universities.
At Eton: the school offers 28 A-Level subjects including 9 modern and classical languages. Years 10-11 (E/D Block) study GCSE; Years 12-13 (C/B Block) study A-Level. Terms are called "Halves," divided into Michaelmas (autumn), Lent (spring), and Summer.
Case Study: Eton College
Eton belongs to the Original Nine public schools, investigated by the Clarendon Commission in 1861 and reformed by Act of Parliament in 1868. The nine are: Eton (1440), Winchester (1382), Westminster (1560), Harrow (1572), Rugby (1567), Charterhouse (1611), Shrewsbury (1552), St Paul's (1509), and Merchant Taylors' (1561).
Despite being called "Public Schools," these are all fee-paying private institutions. The term "public" means they were open to the public at large (anyone who could pay), as opposed to earlier schools serving only local parishes. Dulwich College Singapore shares roots with Dulwich College in London (founded 1619), which is of a similar era and tradition.

Key Takeaways
- 1.British education is exam-driven: 11+ determines secondary school, GCSE determines Sixth Form, A-Level determines university.
- 2.11+ and 13+/Common Entrance are entry exams only needed for UK grammar or elite private schools. Singapore British-system schools do not require them for internal progression.
- 3.GCSE/IGCSE is the most important intermediate exam. In Singapore, TTS, Dulwich, Nexus, and SJII use it. UWC, NLCS, and SAS do not.
- 4.A-Level is 3-4 subjects with depth; IB Diploma is 6 subjects with breadth. In Singapore, only TTS offers both pathways.
- 5.“Public School” in Britain is actually a fee-paying private school—the most confusing term for Chinese parents.
