Hii Hemanth

There is no comparison between national institute of technology warangal and Vellore Institute of technology , Vellore . National institutes of technology are one of the best engineering colleges you can find in India . You should directly go for pursuing Bachelor's in technology from NIT over VIT. NIt is a central government institution and getting admission there is a hard nut to crack . VIT doesn't have that level of competition.

Hope it helps

Thanks
