Three competitive degrees, three different IGCSE profiles. Law, Computer Science and Architecture are among the most popular university courses globally, and the IGCSE subjects that prepare for each are not the same. This guide explains exactly what each pathway wants, what to take, and what target grades make the application competitive.
Law degrees do not require specific subjects at IGCSE in the way Medicine or Engineering do. What admissions tutors look for is a profile that signals strong written communication, analytical thinking and broad academic engagement. The recommended IGCSE profile:
English Language (First Language) — grade 7-9 / A*-A. Critical. Law degrees are writing-intensive; admissions tutors read English grades carefully.
English Literature — grade 7-8 / A. Demonstrates engagement with text analysis and argument.
History — grade 7-8 / A. Excellent preparation for legal reasoning; commonly recommended by Law admissions tutors.
Mathematics — grade 6+ / B+. Required for most Law degrees; some require A* / 7+. Used for evidence-based reasoning and statistical analysis in some Law courses.
A second language (French, Spanish, German, etc.) at grade 6+ / B+. Distinguishes the application, particularly for international Law programmes.
One or two Sciences — grade 6+ / B+. Demonstrates breadth, not specifically required.
Either Economics or another humanities/social science (Geography, Politics if available, Psychology) — grade 7+ / A. Strengthens the analytical profile.
For UK Law degrees (LLB), most universities expect 5+ IGCSEs at grade 6/B or above. Oxbridge and the most competitive UK Law programmes (UCL, LSE, KCL, Durham) expect 8+ IGCSEs with a high proportion at grade 7-9 / A*-A.
For Law at A-Level: there is no required A-Level subject (most universities accept any three), but Law students benefit from A-Level English Literature, History, Politics or Philosophy. Some universities (LSE in particular) expect at least one essay-based A-Level subject.
Computer Science: The IGCSE Profile
Computer Science degrees vary in their requirements but share a strong Maths emphasis. The recommended IGCSE profile:
Mathematics (Extended/Higher) — grade 8-9 / A*-A. Non-negotiable. CS degrees are mathematically intensive (algorithms, data structures, complexity, linear algebra). Below grade 7 / A is a flag.
Additional Mathematics (Cambridge 0606) — grade 7-8 / A. Strongly recommended. Demonstrates higher-level mathematical capability before A-Level Maths.
Computer Science IGCSE (Cambridge 0478) — grade 7-9 / A*-A. Useful but not always required. Demonstrates programming familiarity and computational thinking. Some students benefit from taking this even if Computer Science isn't formally required.
Physics — grade 7-8 / A. Useful for understanding hardware and systems concepts. Most universities prefer to see it.
English Language (First Language) — grade 6+ / B+. Required for English-medium degree entry.
Other subjects to grade 6+/B+. Broad academic profile across 8-10 IGCSEs.
For UK Computer Science: Cambridge Computer Science typically expects A*A*A at A-Level with A-Level Maths required and Further Maths recommended. Imperial CS requires Maths A-Level at A* / 9 plus another science. Oxford CS, MIT, Stanford, ETH Zurich all require strong Maths preparation from IGCSE upward.
For A-Level: Maths (essential), Further Maths (strongly recommended for competitive applications), Physics or Computer Science (depending on focus), and a fourth subject for breadth.
Architecture: The IGCSE Profile
Architecture is unique among degrees — it requires both academic and creative IGCSE preparation, and many programmes require a portfolio at admission. The recommended IGCSE profile:
Mathematics (Extended/Higher) — grade 7-8 / A. Required for structural and spatial reasoning. Architecture combines art and engineering.
Art and Design IGCSE — grade 7-9 / A*-A. Essential for portfolio development. Universities want to see formal art training plus an emerging architectural sensibility.
Physics — grade 6+ / B+. Important for understanding structural engineering principles.
Design and Technology (where offered) — grade 7+ / A. Excellent preparation; combines design thinking with material understanding.
English Language (First Language) — grade 6+ / B+. Required for English-medium degree entry; also relevant for design-justification writing.
Geography (where offered) — grade 6+ / B+. Useful for understanding urban form and environmental context.
One language at grade 6+ / B+. Strengthens the broader profile.
For UK Architecture: typical entry requires three A-Levels including either Maths or a Science plus Art or Design and Technology. Strong UK Architecture programmes (Bartlett at UCL, AA School, Cambridge) require ABB to AAA with a portfolio interview. International programmes vary.
The portfolio is often as decisive as grades. Students aiming at Architecture should be developing a portfolio of drawings, design sketches, and architectural studies from IGCSE Year 10 onward.
What All Three Have In Common
Universal IGCSE requirements across Law, CS and Architecture:
Strong English Language — grade 6/B minimum; 7+/A for competitive courses.
Strong Mathematics — grade 7/A minimum for CS and Architecture; grade 6/B minimum for Law.
Broad academic profile — 8-10 IGCSE subjects across the disciplines.
Consistency — universities read inconsistency across the profile as a flag.
Target Grades by University Tier
For the most competitive courses (Oxbridge, Russell Group, Ivy League):
Law: 8+ IGCSEs at grade 7-9 / A*-A, including English Language, English Literature, Maths and one or more humanities at A*. Strong A-Levels (A*AA-A*A*A) plus LNAT/equivalent.
Computer Science: 8+ IGCSEs with grade 8-9 / A* in Maths, Additional Maths and Physics; grade 7+ / A across the rest. Strong A-Levels (A*A*A with Maths, Further Maths, Physics or CS) plus MAT/STEP/admissions test.
Architecture: 8+ IGCSEs at grade 6+ / B+ minimum, with grade 7+ / A in Maths, Art, Physics. Strong A-Levels (AAB-A*AA with Maths or Science plus Art/Design) plus competitive portfolio.
When Subjects Are Not Available
Two common situations:
Schools that don't offer Additional Maths or IGCSE Computer Science: available as private candidate subjects through the British Council or other approved centres. For students serious about CS or Engineering, sitting these as private candidates is worthwhile. See our private candidate guide.
Schools that don't offer Art at the depth needed for Architecture portfolios: external art programmes, portfolio-development workshops, and private tutoring can supplement school provision. The portfolio is often as decisive as IGCSE grades for Architecture admissions.
Planning IGCSE for Law, CS or Architecture?
Our 1-on-1 tutors prepare students across all relevant subjects — English Language and Literature for Law, Maths and Computer Science for CS, Maths and Art for Architecture. Free diagnostic trial maps current profile against target degree.
Law degrees do not require specific IGCSE subjects but expect a strong profile: English Language at grade 7-9 / A*-A (critical), English Literature, History, Mathematics at grade 6+ / B+, a second language, and breadth across humanities. Oxbridge and competitive UK Law programmes (UCL, LSE) expect 8+ IGCSEs with a high proportion at grade 7-9 / A*-A.
CS degrees require strong Maths preparation. Required: Mathematics Extended/Higher at grade 8-9 / A*-A; English Language at grade 6+ / B+. Strongly recommended: Additional Mathematics at grade 7+ / A; Computer Science IGCSE at grade 7-9 / A*-A; Physics at grade 7+ / A. Competitive CS (Cambridge, Imperial, MIT) expects A* / 9 in Maths and Add Maths.
Architecture combines academic and creative requirements: Mathematics at grade 7+ / A; Art and Design IGCSE at grade 7-9 / A*-A (essential for portfolio development); Physics at grade 6+ / B+; English Language at grade 6+ / B+. Design and Technology (where offered) at grade 7+ is excellent preparation. The portfolio is often as decisive as IGCSE grades for Architecture admissions.
Strongly recommended but not always required. Strong Mathematics (Extended/Higher at grade 7-9 / A*-A) plus Additional Mathematics is the more critical foundation. Computer Science IGCSE demonstrates programming familiarity and computational thinking, which strengthens the application — but Maths is the gatekeeper. Many CS students enter without IGCSE Computer Science but with strong Maths.
Possible but harder. Architecture programmes require a portfolio at admission; IGCSE Art provides the formal training and time to develop work. Students without IGCSE Art who want Architecture need to demonstrate equivalent portfolio capability — external art programmes, portfolio-development workshops, or private tutoring can fill the gap. Adding A-Level Art at sixth form is the most reliable bridge.
No. IGCSE Law is rarely offered and is not required. Law degrees look at the broader profile (English, History, Maths, humanities) rather than specific Law preparation at IGCSE. A-Level Law is also not required — most Law students enter with three A-Levels from English Literature, History, Politics, Economics, Philosophy or similar essay-based subjects.
