Hi ! It seems difficult for you to get nit. It is so because one of the eligibility criteria for sc students to get into nit is that they must get 65% in their class 12 boards. But your sc category JEE main rank is good. So hope you understand and best of luck to you.

Greetings to you,

The eligibility criteria of NITs states that the candidate must have secured atleast 75% (PCM) in class 12th boards. Since you do not fulfill the criteria, you cannot get admission into NITs. But you can try for private institutions that accept JEE Mains score or those who conduct their own admission tests. Feel free to comment for any other query. Good Luck.
