Hello Jarpula Sardhar Naik

Congrats for 78.9 percentile in Jee mains

78.9 is decent score and you are in ST category also so I hope you get seat in Top NIT's but we can't predict this right now because the final rank list and Cutt off list will be published by NTA in april So I think you should wait till april.
As you know there are 2 attempts for JEE mains,1st held in January and the 2nd one would be in april so after april attempt NTA will publish the rank list and Cutt off list .So please wait till april.

i hope you get my point.

Thank You and GOOD LUCK!!!
