NoteThe exported Wix ZIP contained no independent local download files. This page therefore replaces the old collection with more durable selection criteria and topic links.
Five criteria for good learning material
- Fit: matches topic, level and examination format.
- Activity: requires calculation, retrieval, explanation or creation.
- Feedback: includes solutions, criteria or a verifiable reference.
- Progression: moves from foundations to transfer problems.
- Reliability: author, source, recency and correction process are visible.
A useful material mix
Understand
Short explanation, example and visual representation.
Practise
Problems of increasing difficulty with solution checking.
Test
Past papers, quizzes or an independent summary without notes.
Another video does not help when the difficulty is application. A demanding problem set is equally unhelpful when core terms remain unclear.
Continue purposefully
- for Abitur: current school/authority material and exam-style problems
- for IB: official course and assessment documents from the school
- for university applications: official programme pages and personal trackers
- for AI: KAI, primary documentation and controlled experiments
- for careers: JobFutureCheck, work experience and conversations with practitioners
The right resource should enable the next learning step—not merely enlarge a collection.
