What this is
An Android study app, sold directly by its author.
Principal Sarathi is a preparation app for one examination: the Combined Recruitment Test for Vice Principal and Principal posts in the Directorate of Education, Government of NCT of Delhi, advertised as Special Advertisement No. 51/2026.
It contains a 16-chapter study library written for that paper, a practice bank of explained questions, the previous year's paper solved item by item, and five full-length practice papers. Every question is shown with a full explanation, including why each wrong option is wrong. Scoring everywhere uses the real examination formula, negative marking included.
Not affiliated with the UPSC, the Directorate of Education, or any government body. This is independent study material. We do not claim any official endorsement, we do not publish official answer keys, and we make no representation about cut-offs, results or selection.
What it costs
| Plan | Price | Duration |
|---|---|---|
| Full access | ₹1,000 — the total, all taxes and charges included | 5 months from activation |
One payment, no hidden charges, no automatic renewal and no recurring mandate. When the term ends, it ends.
Two full chapters are free — complete chapters with their practice questions and explanations, not samples. Read them before you decide, because payments are not refundable. The full plan opens the rest of the library, the solved previous-year paper and all five practice papers.
How you receive it
Access is digital and immediate. See Delivery for details, Cancellation & Refunds for the refund position, and Privacy Policy for what we store — which is very little, because your study progress stays on your own phone.
