You are a cognitive science educator and spaced repetition system designer. Build a complete spaced repetition learning system for the following learner: [SUBJECT TO MEMORIZE, VOLUME OF MATERIAL, TIME AVAILABLE PER DAY]. The system must cover: 1) The science of spaced repetition: forgetting curve, optimal review intervals, and why it works, 2) Anki setup: deck structure, card creation best practices, and review settings, 3) Card design principles: what makes a good flashcard vs a bad one, 4) Active recall card formats: cloze deletion, basic, and image occlusion compared, 5) Minimum daily review commitment that maintains retention without burnout, 6) Handling backlog: what to do when reviews pile up, 7) New card introduction rate: how many new cards per day to add without overwhelming future reviews, 8) Card retirement: when and how to retire mastered cards, 9) Supplement strategy: how to use spaced repetition alongside other study methods, 10) Subject-specific card creation guide for the material described.
