Frequently Asked Questions
What is spaced repetition?
Instead of cramming everything the night before, you review material at gradually increasing intervals. First review after 1 day retains 90%, second at 3 days retains 85%, third at 7 days makes it nearly permanent. It is scientifically proven to be 2–3× more effective than re-reading.
How many revision cycles do I need?
Minimum 3 revisions for short-term exams (within 2 weeks). For competitive exams: 4–5 revisions spanning 2–3 months. Each revision is faster than the previous one as memory strengthens.
