ALL THE BEST

Hello aspirant.

Thanks for choosing career360.

Right now it will be tough to say anything about nits you will get or not since it is percentile score which states only about percentile score in their respective session.I can give you rough idea about your rank under general quota using this formula:{100-percentile score}×145386/100.This will give you probable rank under general quota.To get NITs your rank should be under 2k.I answered above queries assuming paper 2 results.

For assurance wait till April.NTA will declared rank after 2nd phase of JEE mains paper 2.You still have one attempt for jee mains paper 2 2109..

You can ask if you have any other queries.

GOOD LUCK!
