The IGCSE Computer Science 0478 AI Tutor Prompt Library

The Grademy AI tutor uses a dedicated IGCSE Computer Science 0478 prompt library that simulates every Paper 1 + Paper 2 question type, scores every source-based + theory + programming + 1-mark + 2-mark + 3-mark + 4-mark + 5-mark + 6-mark + 8-mark + 10-mark + 14-mark + 20-mark question against the official Cambridge CAIE 0478 mark scheme, and walks the candidate through every question in real-time. The AI tutor holds the full Cambridge CAIE 0478 specification + mark scheme + examiner-reports + past-papers-library + student-answers-library in working memory.

The AI tutor also adapts in real-time: when a candidate struggles with binary-to-hexadecimal conversion in 4-mark questions, the AI tutor immediately shifts to a 5-question binary-hex sprint + walks the candidate through the division-by-16 + remainder-reading + 4-bit-grouping mechanics + debugging. When a candidate nails algorithm-design but struggles with data-structure-selection, the AI tutor isolates data-structures as a standalone sprint and walks through the array-vs-list-vs-stack-vs-queue-vs-tree-vs-graph selection criteria + operations + Big-O complexity.

The AI tutor's scoring rubric for each question type:

• Source-based 1-mark identification: Identifies the Computer-Science concept by name. Candidate must name the concept (1 mark).
