It is good but Tezpur University is a much better option.

You can check the opening and closing rank for general category by doing some Google Search. I think you have less chances but don't lose your hope and hope for the best.

Go for NITS any day. If you look at the ranking also it is ahead but this year also MHRD ranked it above NITA.
The top branches here at NITS are CSE, ECE, mechanical, electrical, civil.

What is your category?

Silchar does not have any good institute to pursue MBA. You need to come out of your comfort zone and look options in other part such as IIM-Shillong (need CAT percentile of 98% and above) or IIFT-Kolkata or other institutes in east India.
