Quick answer: There are roughly 45–60 GCSE subjects regulated by Ofqual at any time, spanning English, maths, sciences, humanities, languages, arts, technology and physical/social subjects. In school, English language, English literature, maths and science are effectively compulsory; everything else is optional. Adults can take almost any GCSE subject as a private candidate — though written-exam-only subjects like maths, English language, sciences, history and psychology are the most practical to study online.
Whether you're choosing options, planning a return to study, or checking which GCSE a career actually needs, the full subject landscape is bigger than most school option booklets suggest. Here's the complete list by category — and the honest guide to which subjects adults can realistically take.
Which GCSE subjects are compulsory?
In English state schools, the national curriculum makes English and maths compulsory to 16, and virtually all pupils also take science (combined or separate). The government's English Baccalaureate (EBacc) adds a preferred core — English, maths, sciences, a language, and history or geography — that many schools structure options around, though it is a performance measure, not a legal requirement.
For adults the "compulsory" question is different: no subject is compulsory, but English language and maths at grade 4+ are the two that jobs, apprenticeships and universities check — which is why they're the most-taken adult GCSEs by far, and the only two with a November resit series. Our guide to how many GCSEs you need covers working backwards from your goal.
The full GCSE subjects list by category
Exact availability varies by exam board (AQA, Pearson Edexcel, OCR, WJEC/Eduqas, CCEA) and by school; Ofqual's register of regulated qualifications holds the definitive current list. The recognised subjects group like this:
| Category | Subjects |
|---|---|
| Core | English Language, English Literature, Mathematics |
| Sciences | Combined Science (double award), Biology, Chemistry, Physics, Computer Science, Astronomy, Geology, Environmental Science |
| Humanities & social sciences | History, Geography, Religious Studies, Psychology, Sociology, Citizenship Studies, Classical Civilisation, Ancient History |
| Modern languages | French, Spanish, German, Italian, Mandarin Chinese, Japanese, Russian, Arabic, Urdu, Polish, Portuguese, Panjabi, Bengali, Turkish, Greek, Hebrew (and more community languages) |
| Classical languages | Latin, Classical Greek, Biblical Hebrew |
| Arts | Art & Design (multiple endorsements), Music, Drama, Dance, Media Studies, Film Studies, Photography |
| Technology & practical | Design & Technology, Food Preparation & Nutrition, Engineering, Electronics, Construction awards |
| Physical & vocational-leaning | Physical Education, Business, Economics, Statistics, Health & Social Care (via vocational alternatives in some schools) |
Two notes on reading the list. Combined Science is one course worth two GCSEs (graded on a 17-point double scale — our Combined Science guide explains it). And several familiar-sounding subjects (ICT, child development, some vocational titles) have been withdrawn as GCSEs over the years and replaced by vocational alternatives — if a subject matters to you, confirm it's still on Ofqual's register before planning around it.
Which GCSE subjects can adults take?
Legally, any — there's no age limit on GCSEs, and adults enter either through a course provider or as a private candidate at an exam centre. Practically, subject choice narrows around one question: does the subject have non-exam assessment (NEA)?
- Exam-only subjects — maths, English language, biology, chemistry, physics, combined science, history, geography, religious studies, psychology, sociology, business, economics, computer science (now exam-only) — are straightforward for online and private candidates: study anywhere, book the written papers.
- Subjects with NEA or practical endorsements — art, drama, music, PE, food, D&T, and the spoken-language endorsement in English language (plus science practical endorsements at triple level) — need a centre willing to assess and moderate the coursework, which is much harder to arrange privately. Adults can do them, but centre hunting comes first.
That's why online adult provision concentrates on the exam-only list: Lift College's GCSE courses cover maths, English language, English literature, biology, chemistry, physics and combined science, plus history, psychology, sociology, business studies and film studies — one of the widest exam-only subject ranges available online, all on a monthly subscription with a 7-day free trial. Exams are booked at partner centres in the May/June series (English language and maths also run in November — see GCSE resits for adults).
One cost note for adults: studying by subscription rather than per-course changes the maths of taking two or three subjects — you pay for study time, not per qualification — but exam entry fees are always separate and paid per subject to the exam centre, typically £40–£60 per written-exam GCSE at most centres (centre-set, so confirm before booking).
If you need the credential rather than the subject itself, remember the faster equivalent: Functional Skills Level 2 is accepted in place of GCSE grade 4 English/maths by most employers, apprenticeships and many universities — the trade-offs are in our Functional Skills vs GCSE comparison.
Which GCSE subjects should you choose?
For adults, work backwards from the destination:
- Any job/apprenticeship baseline → English language + maths. Full stop; add others only if a specific goal names them.
- Nursing, midwifery, teaching, policing → English, maths, and usually science at grade 4+ (primary teaching requires a science GCSE; check each programme).
- A-Levels or University Preparation Course next → the GCSE(s) underpinning your intended Level 3 subjects — e.g. GCSE biology or combined science before A-Level biology or a University Preparation Course health pathway.
- Career change into a technical field → maths (and physics for engineering routes) carries the most weight.
Choosing more subjects than your goal requires costs time and money without adding value — three well-chosen GCSEs beat six unfocused ones for almost every adult purpose.
