Hey there,

You should go for CSE at IIIT Lucknow. If you want a better exposure faculty and facilities then go for this college otherwise if you to study the metallurgy engineering then you can also go for nit Rourkela. Nit Agartala is not very much good in terms of packages of placement and facilities when you compare it with these two colleges.

So in my opinion just join IIIT Lucknow.

Good luck ahead !
