Built by an engineer who went deep on UPSC.
I'm an engineer who spent months working with UPSC rankers and aspirants — trying to understand examiner psychology and how coachings trap aspirants in a perpetual cycle of costly Mains Test series.
I came to UPSC prep as an outsider — which turned out to be useful. What examiners look for, where coaching feedback fails, which dimensions differentiate a 3-mark answer from a 5-mark answer. I built for that.
LeanPrep is a focused operation built on the conviction that specific feedback compounds faster than more content.
