Hello Sandra, 

With 74.21 percentile in Jee Mains it's not possible to get NITs. But what you can do is to try for some other institutes. 

There are several good institutes in India, accepting Jee Mains score for admissions like LNMIIT Jaipur, Jaypee, Thappar and many more. 

These institutes have a slight higher fee than government's but the campus facility, academics and placements are quite good. 

Hope this will help. 

All the best for future. 

Hey there,

With this much score in jee mains examination you should go for private colleges that should give you a seat in any good branch there like CSE, mechanical engineering etc.

I hope you have got the point.

Good luck ahead !
