250 marks in JEE Main — what percentile?
Type your marks (or drag) and see the expected percentile and All-India-Rank range immediately. Percentiles come from NTA normalisation, which shifts a little every session — so the honest answer is a range, and that is what you get.
Methodology: percentile from a curve fitted to NTA's published normalisation pattern (estimate — NTA issues no official marks→percentile table); rank = (100 − percentile)% of a ~14,00,000candidate pool, shown ±14%. Category conversion is a low-confidence estimate. None of this is an official NTA figure — treat it as orientation, not allotment.
Common score bands
A percentile is a symptom. Your weak chapters are the cause.
Two students with the same 94 percentile lose marks in completely different places. A 15-question adaptive diagnostic finds where YOUR marks are leaking — before the real exam does.
