Many of the engineering colleges in India take admission on the basis of JEE score.
It is not necessary. There are many exams like COMEDK, state level exams like UPSEE,VIT .
But most of government institutions are accepting JEE score only. And, most of good private college too.

JEE paper 1 marks are responsible for NITs and CFTIs. Your 2 paper marks are responsible for IITs only.
