NIT

Hello Aditya Singh,
A person with disability definitely needs to be given an advantage over others, while considering admissions. The issue that confronts doctors is how much percentage of disability actually hinders a person from performing normally. In Indian context this issue has been answered and 40% disability is considered adequate for inclusion of a person in PWD category. I am afraid with only 10%, you will not be eligible to claim benefits under this category.

There are various NIT colleges, which offers different courses, which are given below:-
1) NIT, Silchar
2) NIT, Surat
3) NIT, Warangal
4) NIT, Jalandhar.

Yes, for sure. Go ahead.

Diploma students who have completed their degree, or are in the final year of doing so, are eligible to apply for JEE Main 2018, but will not be given admission to NITs and CFTIs. If they qualify JEE Mains, they will have to appear for JEE Advance, and they will be given admission like class 12th pass students.

Yes, you can get NITs with this score, but I'll prefer you to opt for the School of Planning (SPA) for the B.Arch course as Spans are far better than the NITs.

NIT-Surat is the best. DAIICT is a private college and established in 2001 while NIT Surat in 1961. The selection criteria of NIT-Surat is very tough and top students of their streams get admitted here. So, my choice is NIT-Surat.

Yes.
There may be chances of getting an admission in any NITs like NIT Silchar or NIT Warangal, NIT Surat, etc., according to your JEE Mains percentile.

In OBC, there are two further splits- Creamy layer and Non Creamy Layer. If you fall under NCL, then you have a chance in those bottom rated NITs.
