WJEC GCSE Computer Science Unit 1 revision in one interactive file: notes for every spec area (1.1 to 1.8), quizzes, flashcards, 38 exam-style questions and a progress tracker. Pupils open it in any web browser, and it works offline.

Written by a practising computer science teacher in Wales, for Year 10 and Year 11 pupils sitting the Unit 1 on-screen exam (2025 specification).

What’s inside

• Home: a clear starting point that explains every section and shows each pupil’s progress and what to revise next.
• Topics: revision notes organised by spec number, from 1.1 Computer architecture to 1.8 Systems development life cycle. Each area is colour-coded, key terms are highlighted, and “be aware of” content is labelled.
• Program construction, Logic, Converter and Peripherals: hands-on practice with translators and errors, truth tables, binary/denary/hex conversions and bit shifts, and choosing devices for a scenario.
• Impacts: environmental, ethical, legal and social issues.
• Flashcards: over 200 cards, filterable by topic.
• Quizzes: 14 topic quizzes plus a mixed quiz, with feedback on every answer and best scores saved.
• Exam questions: 38 original exam-style questions (133 marks) using WJEC command words. Pupils type an answer, then reveal the possible answers, level descriptors for extended questions and model answers. Timed practice papers of 20, 40 or 80 marks are included.
• Revision guide: how to revise, a 30-minute session plan, a revision planner, exam facts, command words and exam technique.
• Progress: a red/amber/green “I can” checklist for the whole unit, quiz scores and a “revise next” list.

How it works

The hub is a single HTML file, supplied in a zip with a one-page PDF guide for pupils and teachers. Pupils download it and double-click to open it in a browser. There is nothing to install and no login. Progress saves automatically in that browser, and Save progress and Load progress buttons let pupils back up their work and carry it between home and school.

Good for

• Independent revision and homework
• Pre-mock and pre-exam revision
• Starters and plenaries using the quizzes and exam questions
• Giving pupils one place to go for Unit 1

Please note

This is an independent resource written for the WJEC GCSE Computer Science specification. It is not produced or endorsed by WJEC, and it contains no WJEC past paper questions. You can share the hub with the pupils you teach (for example on Teams or Google Classroom), but not with other teachers. It works best on laptops, desktops and Chromebooks; some tablets and phones can’t open downloaded web files.
