B.Tech Eligibility

Hi there!
My cousin is pursuing BTech from Thapar Insititute and all he has is goof things to say about the institute. You can seek admission through any mode on the basis of a single application form, subject to fulfilment of eligibility criteria.
Mode 1 70% seats on the basis of JEE (Main)-2019/NEET-2019 rankings
Mode 2 - 30% seats on the basis of 10+2 PCM/PCB scores
Their applications are open. Hope check it out.

Yes, in many field class 12th percentage matters.
But, in some fields there is no matter, but you should have more than 60% for safer side.

Good luck.

You have to clear the exam of either JEE Mains or CEE. After clearing, you can take admission in Dibrugarh University.

There are two branches. One is ICT, and the other is ICT+minors in Computational Science. You can register for admission and depending on your overall rank; you will get ICT or ICT+CS.
For admission through GUJCET, you need to score minimum 98% in boards and above 110 in GUJCET. Your overall rank should be in top 250.
I have taken admission through JEE Mains and my all India rank was 10015 and I got admission in ICT.

Sorry, to say this, you are not eligible for that, because it's base cutoff is 75%

Actually, in Sastra University, they won't consider B.Arch marks in admission process. Basically, for getting into Sastra University, there are two processes.
Stream 1: which is JEE + inter marks
Stream 2: only inter marks.
For your son, considering the given data, getting seat is difficult. There is no donation seats. But, some seats are available in NRI quota and NRI sponsored quota.

MNNIT is a top level NIT. With 82 percentile, you have a slim chances of getting into it. Though I would rather suggest to work hard and put extra effort for the next JEE in April. To be added, you can try for some other NITs and if you have a state quota you may get preferred in those.
