Spaced Repetition Engine
Why Spaced Repetition
WITHOUT spaced repetition:
Learn Chapter 1 in April → forget 80% by December → re-learn from scratch
WITH spaced repetition:
Learn Chapter 1 in April → review Day 3, 7, 14, 30 → remember 90%+ in March
Total extra time: ~30 minutes of reviews over a month
Time saved: ~3 hours of re-learning before boards
Review Schedule
Day 0: LEARN (full study session)
Day 1: QUICK REVIEW (10 min — scan notes, recall key points)
Day 3: ACTIVE RECALL (15 min — close book, write from memory)
Day 7: PRACTICE TEST (20 min — 5 questions without notes)
Day 14: MIXED REVIEW (15 min — mix with other chapters)
Day 30: FINAL CHECK (10 min — if 90%+ recall, mark as "locked")
If recall < 70% at any stage → reset to Day 0 (re-learn)
What to Space-Repeat Per Subject
Mathematics
MUST RETAIN: REVIEW METHOD:
All formulas Write from memory, verify
Trigonometric ratios Flash-quiz (sin30°=? cos45°=?)
Mensuration formulas Draw shapes + write formula
AP formulas Quick 2-problem drill
Quadratic formula Solve 1 problem using it
Science
MUST RETAIN: REVIEW METHOD:
Chemical equations Write + balance from memory
Reactivity series Recite order: K Na Ca Mg Al Zn Fe...
Physics formulas V=IR, P=VI, R=ρl/A — write all
Biology diagrams Draw from memory (heart, nephron, neuron)
Process steps Photosynthesis steps, digestion flow
Social Science
MUST RETAIN: REVIEW METHOD:
Historical dates Timeline quiz (year → event)
Map locations Blank map marking drill
Economic data GDP%, HDI values, sector contributions
Constitutional articles Article numbers → what they say
Movement chronology Gandhi's movements in order
English
MUST RETAIN: REVIEW METHOD:
Poem summaries 2-line recall per poem
Author names Title → Author quick quiz
Grammar rules 1 exercise per rule type
Letter formats Write format skeleton from memory
