GCSE Computer Science
Mae disgrifiad y cymhwyster yn Saesneg yn unig, gan ei fod wedi ei gymryd o fanyleb Saesneg CBAC.
Numeracy is heavy and specific: learners convert between denary, binary and hexadecimal, add in binary, work with base 2 storage units, calculate image, sound and compressed file sizes and routing costs, and reason with truth tables and DIV and MOD. Literacy centres on close reading of the Unit 2 scenario and requirements, precise technical vocabulary, short and extended judgement answers in Unit 1, and code annotation and test commentaries. The single biggest thing Key Stage 3 should build is fluent place value in base 2 and base 16, so that storage and file size calculations become routine.

Sgiliau sy'n defnyddio Diben
-
Discussing the impact of computing and AI
The specification expects discussion of the impact of the latest AI tools and collaborative teamwork, and Appendix A ticks speaking and listening for both units. These experiences are not directly assessed.

Paratoi disgyblion
- Blwyddyn 7
- Pupils take roles such as parent, pupil and headteacher in a short group discussion on screen time rules, building on each other's points.
- Blwyddyn 8
- Pupils pair program a Scratch task as driver and navigator, swapping every ten minutes and explaining each choice aloud using the correct terms.
- Blwyddyn 9
- Pupils hold a structured class debate on whether AI should mark coursework, using evidence from two short articles and responding to the other side.

Da gwybod
- No marks are set aside for spelling, punctuation and grammar. The assessment objectives on page 28 cover only knowledge (AO1), application (AO2) and analysis (AO3), so accuracy of language is not separately credited.
- Both units are answered on screen, page 5: Unit 1 is a "Digital examination: 1 hour 30 minutes" and Unit 2 is an "On-screen examination based on a pre-released brief: 2 hours". Pupils need to type extended answers and calculations.
- The specification does not say whether a calculator is allowed in either unit, so centres should check the WJEC instructions for each series. Pupils should be able to do binary, hexadecimal and storage calculations by hand.
- No notes are allowed into the Unit 2 examination, page 28: "learners are not permitted to take any prompts or notes into the examination." A clean copy of the pre-release is provided.
- Unit 1 mixes question types, page 5: "Questions requiring objective responses, short and extended answers."
- Storage units use 1,024, not 1,000, page 13: "kilobyte (i.e. 1,024 bytes)". Pupils who learn 1,000 in Science or Mathematics need the difference made explicit.
- Appendix B, pages 34 to 36, fixes the operators and pseudocode conventions used in questions: "Logical operators AND OR NOT XOR will be in upper case." DIV and MOD are defined with worked examples such as "11 MOD 2 = 1".
- Appendix A, page 32, marks the numeracy strands for geometry and measurement and for statistics and probability as N/A for both units, so there is no graphing or statistics demand.
Cysylltiadau â chymwysterau eraill
Place value, powers, ratio and percentage reduction are taught in Mathematics, so agreeing shared language (for example 'column value' and 'simplest form') with the Mathematics department in Years 7 to 9 will help pupils transfer these skills to binary and file size work.
