Which UPSC subjects are covered?

All seven General Studies Paper I (Prelims) subjects: History, Polity, Geography, Economics, Science & Technology, Environment, and Current Affairs. Cards are organized by topic and weighted to match exam patterns.

How is this different from reading NCERTs?

NCERTs give you the knowledge, but most aspirants forget 80% within a week. We turn NCERT-level facts into active recall flashcards — you type answers from memory instead of re-reading. Spaced repetition ensures you retain facts until exam day.

When should I start using this?

Ideally 6-12 months before Prelims, but even 3 months of consistent daily reviews makes a difference. The earlier you start, the more static facts you'll have locked in.

How much time do I need per day?

Most users spend 20-30 minutes per day on their review sessions. This complements your main study — think of it as a retention layer on top of your reading.

Is there a mobile app?
