Who does it and how:
- Coaching centre operators (Tier 2–4 cities): Solo or 2–5 person setups. Manage 20–200 students. Teacher inputs a chapter name; a staff member (or the teacher themselves) copies questions from a guidebook or past paper PDF into a WhatsApp message or a printed sheet. Payment tracked in a paper register or Google Sheet. No automated progress tracking.
- Individual tutors (WhatsApp-first): A tutor with 10–30 students sends daily practice questions over a WhatsApp group. Parents send photos of completed work back in the group. The tutor marks it at 10pm after other work. Feedback is a thumbs-up emoji or "see question 3."
- Parents doing it themselves: Parents of CBSE students in Classes 1–8 download worksheets from websites, print them, sit with the child, and check answers themselves. No mechanism to know if the worksheet matches what the child actually needs today.
- YouTube as the default free tutor: Channels with百万 subscribers (Vedantu, Physics Wallah, others) produce lecture content. But lecture ≠ practice. Children watch and forget. Parents have no way to convert passive video watching into active retention checking.
- Teacher time absorbed by manual question selection, worksheet sourcing, marking, and parent communication — work that does not scale past 30–40 students per teacher.
- Coaching centres run on 60–70% teacher take-home; the owner retains 30–40% gross. A tool that lets one teacher handle 80 students without quality loss is the actual value.
- Parents pay ₹500–₹2,000/month per child for tuitions and ₹300–₹800/month for an app subscription. They cannot easily assess whether either is working.
