Every Indian state board has its own tutor here — the boards that examine on NCERT read the NCERT chapters under their own name, and the boards with their own textbooks get chapters written to those books. Each chapter explained, with practice and notes in English and Hindi. Free, no sign-up.
The badge on each card names the textbooks its chapters follow: NCERT where the board prescribes NCERT, the board’s own series where it publishes its own.
