NIT Agartala - National Institute of Technology Answered Questions

Actually, the fee of all NITs is not same even semester fee of NIT-Agartala is not same as the hotstel fee of all semsters. It is 18000 (including mess) and tuition fee varies according to the semester, but approximately INR 70,000 per semester (after batch 2015_19) because the policy of MHRD has been changed from 2016, but if your family income is less than 1.5 lakhs then you need to pay the half of tuition fee.

Both the institutes are almost at par with NIT Jalandhar on a little upper hand. Opt for the engineering branch that you love the most and are most passionate about and analyze the future work conditions, scope and growth prospects before taking admission.
You can also opt for psychometric test comprising of aptitude, personality, and career interest to clear confusion.

I think you should go for NIT, Silchar CSE without any 2nd thought. One thing I would like to point out that NIT, Silchar is not one of the 'lower' NITs. CSE is the blooming sector everywhere in India, and here, placement opportunities are excellent. NIT is an institute of National Importance. It's directly under MHRD whose standards will be maintained. Fee is comparatively very less in NIT.
Placements (CSE): Not to be biased, CSE of NIT Silchar has taken a delayed take-off in terms of placement. This year's (2016) placements included biggies like Goldman Sachs , Price Waterhouse Coopers, Wells Fargo, SAP Labs, Samsung R and D, Snapdeal, C-DOT (PSU),DRDO, etc. which hired almost 50% of the CSE batch, while most of the remaining got decent offers as well. Which is, if not better, at least quite at-par the Bengaluru colleges. It takes a lot of effort for any company to come to Silchar (They need to invest at-least 3 days for a job they could have done in 1 day, but they still come investing all the time and money). This shows the respect that this brand has.

Level of education is very high and serious here. A guy would struggle if he takes it to be a stereotypical B.Tech college. Almost all the professors have masters and doctoral from the leading IITs of the country. Some of them have also went for research abroad.
Regarding placements, the first batch of electrical and civil engineering students graduated in 2017 and the first batch of mechanical students will graduate in 2018. Half of the guys sitting for campus selection got placed with a highest package of 8.5 lakhs INR pa. Those are really encouraging signs.
