hey there,

you did good!

Well in order to clear the cutoff for General EWS category you need to score more than 78.21 percentile as according to the 2019 JEE mains cutoff.

Since,you scored more than the cutoff, you might get some government colleges.

but, in order to get admission in any NITS you need to score more. So you might not get any NIT or GFIS 

All the best!

Actually it is a bit difficult to get seats in NITs as you are from general category. To get seats in NITs one need to score minimum 98 percentile from this category.you might get in the other but you might have to compromise on the branch choice. You may try to get seats in private colleges too. 

Hope this helps.
