Good Luck.

ECE at NIT will be a better option than techno India salt lake CSE if you don't have an interest in CS or don't know anything about coding. NIT has better infrastructure, faculty, placement opportunity and also the environment.

Sorry dear, no chance at this rank in any NIT.

NIT Agartala is the Second Best after Silchar in NE states. Thus as per my view I would suggest you to go for SILCHAR -NIT is the best in terms of Placement
Infrastructure, Environment. Etc. Thus this purely on my views and as per this factor.

Go for Osmania University if you don't want in the NE states. Osmania University is all good in terms of many aspects and comparable to NITs of NE.
First of all, every college is good. Everything depends on the students and how he/she is. Thus as per the question, my answer will be if you choose NIT, then go for Agartala or Silchar, else choose OSMANIA University.

I would Suggest to go for NIT Silchar for mechanical or even Agartala is also better option among all as per my view as NIT - Agartala and NIT- Silchar have a good placement as per last 3year track record. And thus, the question for your answer is Silchar NIT is best for Mechanical as per view.
