Why one mark can move thousands of ranks
Rank distribution changes with paper difficulty, number of candidates, score clustering and tie-breaking. The relationship is therefore not linear. Near dense score bands, a small mark difference can create a large AIR change.

Once NTA publishes the score card, stop relying on expected-rank articles and use the printed AIR. College prediction and counselling decisions should begin with official AIR and verified eligibility claims.
RankMint’s public calculator is an estimate. It must not be described as an official NTA rank list.
