The people behind UPSC Gurus.
Dr. Bachittar Singh
The Civil Services examination has always asked one question beneath all its papers: is this person ready to serve? The institution that helps a young mind answer yes, honestly and completely, is doing something that matters.
Mrs. Inderjeet Kaur
Genuine preparation is rare. Most aspirants are taught what to write. The ones who are taught how to think carry that with them into service, and it shows, for the rest of their careers.
Ms. Guranchal Singh
We built UPSC Gurus because I believed every aspirant deserves preparation that sees them as an individual, not as one of a batch. That belief is in every program, every session, every evaluation we give.
