Your X Factor.
UPSC doesn't only set Civil Services. It also sets CDS, CAPF, CGS and more — and the same ideas keep coming back across them. X Factor puts those real questions in one builder, by subject and theme, and turns your choices into one timed paper built for you.

builder that brings them together — sorted by subject and theme, timed and marked like the real thing.
The insight
The same idea. Asked by UPSC, again and again.
One concept can turn up in Civil Services, then in CDS, then in CAPF — worded differently each time. Students who only practise CSE papers meet it once. X Factor students can meet it every time it was asked.

Why we built it
Aspirants rarely fail for lack of effort. They fail for lack of direction — and UPSC's own questions are the clearest direction there is.
