How Spaced Repetition Works
🧠 The Forgetting Curve
- Ebbinghaus (1885) showed we lose ~50% of new information within 24 hours.
- After 1 week, only ~25% remains without revision.
- Each successful recall flattens the curve — material is retained longer.
- By revision #5, retention can reach 90%+ for months.
⏰ Why These Intervals?
- 1 day: Catches the steepest part of the curve — when forgetting is fastest.
- 7 days: Forces medium-term recall before total decay.
- 21 days: Embeds material in long-term memory.
- 60 days: Tests durability — if you recall, it's truly learned.
- 120 days: Final consolidation — material is exam-ready.
📅 Which Schedule to Pick?
- Standard (1-7-21-60-120): Best general-purpose. Use when prep is 6+ months away from Prelims.
- Intensive (1-3-7-14-30): Use 1–2 months before Prelims for last-minute topics.
- Long-runway (2-14-45-90-180): Use during foundation phase (NCERTs, Year 1) when retention horizon is 6+ months.
💡 Tips for Good Revision
- Active recall > passive re-reading. Cover the book and try to recite key points before checking.
- Test yourself with PYQs for that chapter — that's the most exam-aligned revision.
- 10–20 minutes per revision is usually enough for a chapter — don't re-study from scratch.
- Mark as done only if you truly recalled. If you blanked out, leave it for tomorrow.
- Group similar topics for revision sessions — e.g., revise all Mughal-era chapters together.
Frequently Asked Questions
Is this based on real research?
Yes. The intervals are derived from Hermann Ebbinghaus's forgetting curve research (1885) and refined by Sebastian Leitner's box method and modern spaced repetition systems (SRS) like SuperMemo and Anki. The specific intervals match what UPSC toppers describe in their strategies (Anudeep Durishetty, Tina Dabi, Kanak Aggarwal).
What if I miss a revision date?
Don't reset — just revise as soon as you can. The schedule shifts the remaining revisions forward, but doesn't restart from day 1. Missing one revision doesn't ruin spaced repetition; consistent missing does.
What's the difference between Standard and Intensive schedules?
Standard (1-7-21-60-120) is the textbook Ebbinghaus + Leitner method. Intensive (1-3-7-14-30) compresses revisions for last-minute prep — use this 1–2 months before Prelims so all your chapters get a fresh recall just before the exam.
How many chapters can I track?
Unlimited (storage permitting — typically 10,000+ entries in localStorage). For UPSC, expect to track ~200–300 chapters across all subjects. The tool handles this comfortably.
Can I sync across devices?
Not automatically — your data is stored locally for privacy. Use Export JSON on one device and Import JSON on another to sync manually. Best practice: export weekly as a backup.
Should I do all 5 revisions for every chapter?
Ideally yes for high-yield topics. But realistic: complete all 5 for Static GK, Polity Constitutional articles, and Core History/Economy chapters. For less critical material, 3 revisions are often sufficient.
