What is Spaced Repetition?
Psychologist Hermann Ebbinghaus proved that memory doesn't fade instantly—it decays over time. To stop this, you must revise at specific "Forgetting Intervals".
Immediate Review: Stops the initial 70% data loss.
Quick Glance: Just a look brings retention back to 100%.
First Recall: Moves info to mid-term memory.
Weekly Lock: Strengthens neural pathways.
Permanent Memory: Topic is now Exam-Ready.
The Practical Problem
This sounds perfect in theory, right? But practically, it's a nightmare.
Imagine tracking revision dates for 500+ GS topics, 1000+ Vocab words, and Current Affairs manually. Using Excel sheets, sticky notes, or diaries creates chaos. You end up spending more time planning than actually studying.
