Well, I know it sounds bit awkward but owing to yourcategory and PwD reservation you have a great chance to get into the medocre NIT.

As, since PwD candidates clearing the JEE mains, are so small, so many of their seats are left vacant, holds true for even at top NIT's.

So, I would recommend  you to explore your interest and to find which particular engineering branch suits most to your interest.

Hence, I would recommend you to fill the JoSAA counseling accordingly. Don't hesistate yourself from filling the choice of even top NIT, as nobody knows when the destiny falls into your fate.

Thank You
