Hello Aakanksha,

congratulations for getting good rank in JEE mains 2020. According to your rank and last year cut offs for the NITs sorry to say but you have very very less chances of getting admission into good NIT with good branch. As NITs are the second most recommended institutions in India after IITs so that the cut offs for NITs are very high generally.

You should go through the last year cut offs for all the NITs which will clear your all doubts regarding cut offs and your admission chances. The link for it is provided below.
