Every question is traceable to a defined source: NCERT, the standard reference for that subject, a government document, or an established prelims pattern. No question rests on a detail that has no reachable source.
Calibrated to the observed range of the 2020 to 2026 papers, not to a fixed cap. Sectionals sit at or slightly above the real level, because a sectional is a diagnostic. Full lengths reproduce the actual envelope including its hardest points. What is never permitted is difficulty manufactured by obscurity: a question is hard because it demands reasoning or careful reading, not because it names something no reachable source contains.
Each solution explains why the correct option is correct and why each incorrect option is incorrect. Where a question is eliminable by reasoning rather than recall, the elimination path is shown explicitly.
Published within 48 hours of each test, with marks revised where a question is withdrawn.
Enrolment opens on 1 Oct 2026 and the series begins on 15 Jan 2027. Leave your details and you will be told the day enrolment opens, with a place held for you. This is not an account and there is nothing to pay yet.
