When choosing an international programme, it helps to understand each system’s structure, assessment model, and typical destinations before matching it to target universities. This article summarises five common routes and three exam boards widely used for A-Level/IGCSE in mainland China. Always confirm current rules on official exam-board and university websites.

1. Five common international programmes

1. IGCSE (International General Certificate of Secondary Education)

• Role: The international version of the UK GCSE, often used as preparation for A-Level or the IB Diploma (typically ages 14–16).
• Subjects: Students usually take 5–10 subjects across languages, maths, sciences, humanities, and arts.
• Grading: Most schools and boards now use the 9–1 scale (9 highest); older A*–G grades still appear in some records.
• Use: Builds foundations for later qualifications; some UK universities may consider IGCSE results in admissions. A strong IGCSE English grade can satisfy English-language requirements at some institutions—not all.

2. A-Level (Advanced Level)

• Role: UK advanced academic qualifications, widely accepted for UK, Hong Kong, Australia, Singapore, and other destinations.
• Structure: International routes are often two years (AS + A2 or an equivalent two-year linear course); students typically take 3–4 subjects in depth.
• Features: Fewer subjects, greater depth; STEM combinations (e.g. maths, further maths, physics) are common for engineering applications, but requirements vary by institution.
• Assessment: Mainly external exams; some boards allow modular units and retakes (see exam-board table below). Top universities may require additional tests such as STEP or MAT.

3. IB DP (International Baccalaureate Diploma Programme)

• Role: A two-year pre-university diploma recognised by universities worldwide.
• Structure: One subject from each of six groups (language A, language B, individuals and societies, sciences, maths, arts or another elective), plus TOK, EE, and CAS.
• Grading: Subjects scored 1–7; up to 3 bonus points from TOK + EE; 45 points maximum.
• Features: Breadth, research, and writing are central; internal assessment (IA) counts toward final grades. The 2025-first-assessment science syllabuses (including Physics) removed Paper 3 options and changed exam structure—see IBO official guides.

4. AP (Advanced Placement)

• Role: College Board university-level courses; not a standalone high-school diploma.
• Structure: Students choose AP subjects alongside their main programme; about 40 subjects are available.
• Grading: 1–5 per subject (5 highest).
• Features: Often combined with US high-school GPA and standardised tests for US applications; some universities grant credit. Several subjects now use Bluebook digital exams; science papers place more weight on experimental design and written explanation.

5. DSE (Hong Kong Diploma of Secondary Education)

• Role: Hong Kong’s senior secondary exam; answers may be written in Chinese (traditional or simplified) or English depending on subject.
• Structure: Four core subjects (Chinese, English, maths, citizenship and social development) plus 2–3 electives.
• Grading: Core and elective subjects use levels 1–5, 5*, 5**; citizenship and social development is Attained / Unattained.
• Features: English is a major threshold for local public universities (level 3 is a common minimum, roughly comparable to IELTS 6.0—only a rough guide). Students transferring from mainland systems often need sustained English preparation.

3. CIE, Edexcel, and Oxford AQA (A-Level / IGCSE)

These three boards appear frequently in international schools in mainland China. Syllabuses, paper structures, and mark schemes differ even for the same subject title.

Dimension	CIE (Cambridge)	Edexcel (Pearson)	Oxford AQA
Background	Cambridge International, global focus	Pearson; includes IAL	Oxford University Press + AQA
Exam structure	Often linear (exams at end of stage)	Often modular (unit exams)	Often modular
Retakes	Usually retake by paper group within a session; less flexible	Unit retakes; best marks retained	Similar unit retake model to Edexcel
Sessions	e.g. May–Jun, Oct–Nov	e.g. Jan, May–Jun, Oct–Nov	e.g. Jan, May–Jun
Sciences (broadly)	More calculation and derivation	More context and written explanation	Direct wording; designed for non-native English speakers
Practical work	Some subjects include live practical work	Often assessed in writing	Mostly written assessment

4. Practical notes on choosing

1. Start from target country and degree, then check typical subject combinations and minimum grades—not from which qualification sounds most prestigious.
2. Clear subject strengths: A-Level or AP usually offer more flexibility than IB DP; IB suits students who can work across six groups plus TOK and the extended essay.
3. Hong Kong or DSE-track schools: Compare transfer cost against A-Level/IB; assess whether English can reach the required level on your timeline.
4. Within A-Level/IGCSE: If staged exams and unit retakes matter, look at Edexcel and Oxford AQA; if you prefer linear, calculation-heavy papers, look at CIE—always match the student’s strengths and what the school actually offers.
5. For syllabus changes, digital exams, and language waivers, rely on current documents from exam boards and universities.
