B.Tech Eligibility

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.

BITS, Pilani does not offer lateral entry in B.E(Hons.) programmes.

Hi,
For admission in NCU, you have to first look for the eligibility criteria and make sure you are eligible. The eligibility criteria can be found in the link: http://admissions.ncuindia.edu/Eligibility-Criteria.php
If you are eligible, you have to fill the application form. The link for the application form is: http://admissions.ncuindia.edu
Admission to the university programs will be done on Merit basis. A merit list will be announced for eligible candidates for each round and the shortlisted candidates will be intimated to appear for counselling.

You have to appear for JEE /CET exam, and also HSC exam.
There is 50% importance to each exam score.
If your total percentile is above 90% then there are chances of you getting in COEP.
If you belong to any reservations then you will definitely get in COEP and Instrumentation.
Thank you.

Hi, you have a fair chance of getting into SASTRA. Do download the application form from the website and apply.
All the best!

Yes, you can get admission for B.Tech lateral entry, but you will not get admission in top colleges.
