Trust note
Use official portals for final decisions
Raw marks, percentile, and rank decisions are final only when released by NTA.
College and cutoff tools are planning aids. Seat allotment depends on official JoSAA/CSAB rules and rounds.
Prediction calculators show ranges because exact future outcomes cannot be known from static inputs.
