Computer Science
Daily-habit recall for GCSE Computer Science — algorithms, programming, data, computer systems, networks, cyber security and databases. Built against the published specs of every UK board. Three minutes a day, the same model that works for Maths-adjacent subjects like History and Geography, tuned for the spec a CS teacher actually delivers.

UK GCSE entries / year
Computer Science sits comfortably in the top 15 GCSE subjects by entries and is one of the fastest-growing — entries have roughly tripled since the spec moved from ICT to CS in 2017. Schools are short on revision tools that match the daily-habit model.
4/4
Boards in scope
AQA 8525 (first teaching 2025, first exam 2027), OCR J277, Edexcel 1CP2, Eduqas C500QS. Every spec topic enumerated against the published board PDF, with the AQA YAML at full subtopic depth and the others ready for matched board batches.

Words per answer
CS terms are short and precise — RAM, ROM, ALU, TCP, primary key, fetch-execute cycle, Huffman coding. Perfect fit for the recall card mechanic that already drives Educator's other STEM subjects.
What's covered
Spec-faithful. Board-aware. Validated by the linter.
CS has tight, technical content with very little wiggle room. That's exactly what the spec-anchored card model is built for — every card maps to a numbered objective in 3.1 to 3.8 (AQA), or its equivalent in OCR / Edexcel / Eduqas.

1,170 cards. Spec-anchored, mechanically validated across all four boards. Every card maps to a numbered objective in the spec — AQA 3.1–3.8, or the equivalent in OCR J277 / Edexcel 1CP2 / Eduqas C500QS. CS content mixes technical accuracy (where one wrong distractor reveals a fundamental misconception) with pedagogical sequencing across Paper 1 (computational thinking + programming) and Paper 2 (theory). Authored against primary documentation: Wikipedia, IETF RFCs, Python docs, NCSC guidance.
