SCOPE

Independent practice material, not an official IB product, complete syllabus coverage guarantee or exam prediction. The fictional Studio NovaFrame case and technical enrichment do not replace the prescribed official case study. Teachers should review suitability before classroom assessment. Grade bands are school planning assumptions, not official grade predictions.

AI AUTHORSHIP

AI-generated and AI-reviewed: text and code produced with Gemini and Codex, edited and checked with AI tools. No claim of human teacher authorship or external examiner review. Both included code test suites ran locally; tests do not guarantee every possible input or educational suitability.

USE

Requires a PDF reader, compatible spreadsheet app, and Python 3 or Java 17+ for code. Supply separate answer paper. Not affiliated with or endorsed by the International Baccalaureate.
