Hi Dudam 

There are lots of colleges apart from NIT which have the same standard as NIT.I would like to list the names of such colleges:

BITS PILANI

IIIT HYDERABAD

VELLORE INSTITUTE OF TECHNOLOGY

MANIPAL INSTITUTE OF TECHNOLOGY,KARNATAKA

PSG COLLEGE OF TECHNOLOGY,COIMBATORE

BMS COLLEGE OF ENGINEERING

RAMAIAH INSTITUTE OF TECHNOLOGY,BANGALORE

SRM UNIVERSITY ,CHENNAI

All of these colleges are best you won't regret taking admission in any of them if by chance you failed to get NIT.But your first priority should be to get NIT.

All the best.
