Cramming works for tomorrow morning's quiz. It fails completely for board exams covering 15 chapters across 8 subjects.
The Forgetting Curve
Hermann Ebbinghaus proved that within 48 hours of learning a concept, students lose up to 70% of the details unless actively retrieved. Traditional study patterns exacerbate this through linear chapter reading.
The Optimal Spaced Schedule
Retrieval should occur at expanding intervals: Day 1, Day 3, Day 7, Day 16, and Day 35. Iris AI dynamically schedules question prompts according to your past error rate, resurfacing weak chapters right before memory decay sets in.
