About the WJEC GCSE The Sciences (Double Award) Exam
Made-for-Wales GCSE The Sciences (Double Award) is WJEC’s integrated double-award science GCSE for first teaching from September 2026 (first award summer 2028). It covers living systems, matter, forces and energy, and scientific enquiry across seven units: Biology Basis of Life and Continuity of Life; Chemistry substances/behaviour and bonding/reactions/resources; Physics forces/motion/universe and waves/electricity/energy; plus Unit 7 Scientific Enquiry (two practical-plus-written enquiries). Assessment is unitised and tiered (Higher A*–D; Foundation C–G), available in English and Cymraeg, and supports progression to A level sciences. Separate GCSE Biology, Chemistry and Physics remain available in Wales for at least three years alongside. This free 100-question bank is an English-language MCQ study adaptation only — it does not replace timed structured papers or real practical enquiry work.

Frequently Asked Questions
What is Made-for-Wales GCSE The Sciences (Double Award)?
It is WJEC’s Qualifications Wales–regulated integrated double-award science GCSE (Qual Code 3455QD) for first teaching from September 2026 and first award in summer 2028. Learners study biology, chemistry and physics with scientific enquiry across seven units and receive a double grade from A*A* to GG. It is not available to centres in England and is distinct from England’s GCSE Combined Science: Trilogy.
How is the qualification assessed?
Six tiered external written examinations (Units 1–6, each 1 hour 15 minutes) plus Unit 7 Scientific Enquiry, in which learners complete two enquiries from a choice of three (each enquiry: 1-hour practical task and 1-hour written task). All assessment is marked by WJEC. Official papers use structured written and practical formats; this practice bank is an English MCQ study adaptation only.
What does the double award cost?
The WJEC 2026/27 full qualification centre entry fee for GCSE The Sciences (Double Award) is £93.60. Schools and registered centres pay WJEC entry fees. Students do not normally pay WJEC directly; private candidates are charged by the centre that enters them.
How does this differ from separate GCSE Biology, Chemistry and Physics?
The Sciences (Double Award) is one integrated double-award qualification covering all three disciplines plus scientific enquiry. Separate GCSE Biology, Chemistry and Physics remain available in Wales for at least three years from September 2026 alongside The Sciences and Integrated Science (Single Award). Centres choose the pathway that best fits their learners; separate sciences may suit those aiming for three science grades.
Is this the same as GCSE Combined Science: Trilogy?
No. Combined Science: Trilogy is an England (typically AQA/Edexcel 9–1) pathway. Made-for-Wales GCSE The Sciences (Double Award) is a Qualifications Wales / WJEC qualification graded A*A*–GG, unitised with Unit 7 Scientific Enquiry, and aligned to the Curriculum for Wales. Content and assessment structure differ; use the Wales-specific specification.
What languages is the exam available in?
Assessment is available in English and Cymraeg (Welsh), matching the bilingual delivery of Made-for-Wales GCSEs.
