NIT

Hello Abhilash,
The only way to get admission is to study well and score good marks in JEE Mains. Aim for marks in the range of 300+ and you will get admission in NIT.

Hello Aniruddhaddha,
Even though you must be in one of the NIT's by now, let me answer for benifit of others.
After declaration of results, you have to register yourself on the admission site and fill up all the required data.

250+ for the general category.

Hello Suman,
I am afraid that the score of only 90 is not good enough for admission to NIT. I would advise you to aim for much more marks in next year's exam if you do not get admission this year.
Best wishes.

Dear Madhavi Agarwal,
The fee structure in all NITs for MBA would be less than Rs. 50, 000 on an average in the country but few are good remaining all are not performing well. Amongst good NITs are NIT-Agartala, NIT-Warangal, and NIT-Trichy.
All the best.

Hello Aditya,
The concession is available to PWD in cutoffs. Normally cutoffs are lower than normal, but then you have to be in higher strata of rank. For top NITs, you need to score around 300.

Hello Purnavijay,
I feel, if you have rank around 35000 you should get admission in a NIT. For admission in a better NIT may be you should get good rank than this.

Hello Biraj,
Different scores are required for different NIT's. Older and famous colleges require higher while those who have yet to show mettle require less. Around 250 is required to get admission and around 300 for better institute.

Yes, it is according to the new eligibility criteria of 2017. 75% marks are necessary for their particular board or top 20 percentile in board to get admission in IITs and NITs.

If you want to get admission in good IITs and NITs , you will have to score nearly 300 marks in JEE Mains exam. Then, you have to appear for JEE Advanced exam. If you will get good marks in both exams, you will get really a very good IITs and NITs.
Same advise for IIST. JEE Mains and Advanced exams are required to get admission in IIST.
