National Institute of Technology (NIT Silchar)

Average package of electronic and instrumentation engineering is around 4-5 LPA. It is not a good option to choose. You should go with electronic and communication.

I think IIIT-Sricity is better than NIT, Silchar. As IIITs follow the curriculum of IIIT Hyderabad, which is one of the top universities in India.

I would like to inform you that IITs and NITs both are very big names for B.Tech in India. In these institutions no matter in which part of India you are from you will do well.

NIT-Silchar is the better than IITRAM in terms of placement. Last year, placements were really good.

As per the latest 2018 NIRF-MHRD ranking of engineering colleges in India these institutes are ranked as:-
NIT, Durgapur- 47.
NIT, Silchar- 57.
NIT, Hamirpur- 64.
Best of luck.

I am not know about chemical in VNIT very well but in SVNIT chemical is good. Now a days chemical branch is on progress in SVNIT.

Among the two, NIT-Warangal is better than Silchar for CSE. Hence as per your interest choose the branch which you like the most.

ICE from NIT Jalandhar will be a better choice. As it deals with both instrumentation and control part and now controlling has greater influence
NIT may have the chill life, but, at the end of the day you get a job, a way of life, opportunity to work with some of the latest gizmos and also pride along serving your country. Good luck.

Yes, NIT-Silchar is good for instrumentation. You may consider the same.

18k rank in general category is very high. If you have got NIT Silchar, then it is not confirmed that you got the choice branch. Use prediction tool of Shiksha. For college prediction, refer to this link:
