Which is the best B.Tech branch offered by NIT, Kurukshetra?

All branches are the best but it depends on your interest. I think after giving the JEE, we don't know what's our interest is, somebody knows their Interest and they take decisions based on interest. But most of the students don't know their passion.

On placement basis CSE and IT are best there are fetch the highest package followed by mechanical, ECE amd EE respectively. Civil engineering also has a good reputation over there. So, chose with your interest. Good luck.
