I'll prefer you to opt for the NIT, Tripura as this college has better placements than NIT, Warangal in Metallurgical and Materials Engineering.

Hello Saikumar, The seats in these institutes are set to increase gradually every year due to various factors. Presently there are approximately 40000 seats and all of these are filled up through JoSAA. The exact increase will be announced by government Of India in consultation with individual institutions. Best wishes to you.

It depends on the category. However, wait till 30th April, you will get your rank.
All the best.

Hi,
There are a lot of NATA training centers which make you prepare for NATA exams. Also, there are a lot of solved question banks for NATA and JEE Paper 2 exams, that would be helpful for you, more than this the sketching ability improvement would be a great addition for these exams. Let me know the location in which you are searching for the coaching centers in Bhopal.

Hello,
To score 90 percentile in JEE Mains is quite good. I am sure with this percentile a student will get a seat in his desired NIT and definitely in one of the NIT's. As a matter of fact with this percentile the student will be clearing JEE Mains and will be eligible for appearing in JEE Advanced also. With this in mind the student should not be contented to accept the seat in NIT but study well and bid for a seat in IIT by clearing JEE Advanced. Best wishes to you for your preparation and clearance in JEE Advanced.

Yes, you will definitely get NIT, but not the desired one, and you will not get your desired branch until and unless you are from reserved category.

Hi Sai,
As your son scores are quite good so there are bright chances of him getting CSE at the best NIT. So, don't you worry only you have to be careful during the counselling session.
Good luck.

NIT-Trichy and NIT-Warangal are the best options for metallurgical and materials engineering.
