Questions
Frequently asked questions
13 chapters of the new NCERT book, from Exploration: Entering the World of Secondary Science to Earth as a System: Energy, Matter, and Life. The curriculum above lists every chapter and its lessons.
No. It is a self-learning course that stays open all week. Your child logs in whenever it suits, and nothing is missed by being away.
Yes. Every chapter of the NCERT book is covered, practice papers follow the school exam pattern, and the report shows which topics need another week before a test.
Not yet. Every child gets free Maths practice today. Video lessons and a dedicated teacher are coming soon — we will announce them here.
Three to four hours a week suits Class 9, a little more in the weeks before exams. Your progress view shows the actual time so you can adjust.
For now, yes. Science, English and Social Science are being built and will open here as they're ready.
The chapters are all open from the start, so your child can follow the school's order exactly rather than ours.
Science prices are coming soon. Message us on WhatsApp and we will tell you as soon as they are set.
There is nothing to cancel today — Maths practice has no subscription. Once paid plans open, cancelling will be a tap in your parent account.
