hey there,

Well in order to clear the cutoff for jee main, as for the general category you need to score more than 75 percentile.

This year's cutoff was 78.212 for NIT for the general category.

Yes you can get admission in NIT colleges, but the required branch may or may not be available .

you can look for the following IITS for ECE:

NIT Jalandhar

NIT Jaipur

MANIT BHopal .

etc

ALL the best!!
