Hello Aishwarya,

I would like to congragulate you on your score first.

Secondly, I would like to tell you that you have very low chances of getting into one of good NIT's.

You may have not  have a chance to get any good branches like CSE at the top NI Tbut you can  try for other branches at top NIT's as well as you belong to OBC category.

I would suggest you to visit the careers360's link below which has a detailed explanation of the cutoff for NIT's.

The link for the same is:https://engineering.careers360.com/articles/jee-main-cutoff-for-top-nits

Hope this helps and if you have any more doubts, feel free to comment down your query in the comments section below.

All the very best to you!
