Hello Dear,

Chances of getting NIT on this marks is very less. But as per my openion you should wait for the counselling. On this marks your percentile must be between 95  - 96 and general rank between 46076 - 36253. https://engineering.careers360.com/articles/jee-main-marks-vs-percentile

But as you know the cutoff changes every years because it depends upon the number of seats available, the difficulty level of paper and number of candidates writing the examination hence varies every year depending on these factors. It also depends on home state and other state as you have not mentioned your home state. You can check out your rank on the basis of your score from the below link.
