Hello Hifja,
It would be difficult to provide you the exact qualifying score or admission cutoff 2019 as JEE Main is being counducted twice by NTA for the first time. As a total No. of 1,45,386 candidates had appeared for January Session, Using the Formula (100-your score)* 1,45,386 / 100- Your Expected rank will be around 2,878.
Based on this score the chances seems less to get a seat in top NITs. You can check the previous year cutoff to take an Idea about the admission possibilities.

NOTE: This is only the prediction, To know the actual detail I would suggest you to wait till it officially announced.
Good Luck!
