UPSC CSE · Prelims

Prelims, taught and tested.

Thirteen years of real questions, a tutor who teaches the sources those questions come from, and a mock engine that scores the way UPSC does.

Questions and answer keys are UPSC's own (2014–2026). Explanations are written by the UPSC Answer Check team and are being verified one by one — report anything that looks wrong from under the question. Guru teaches from government-published sources (NCERT, NIOS, IGNOU, Tamil Nadu SCERT, Economic Survey, Union Budget, Constitution of India) in his own words; nothing is reproduced as a book. English only.
