Well, the answer is no since 23 marks is very low for getting admission in any top institution.

For OBC, Generally more than 300 is sufficient to get into Nits but depends on which branch you want to get in. For CSE branch minimum 473, For ECE 352 etc. Hope this will help you. Thank you !

Yes, they provide admission in Masters through both GATE score and BITS HD online exam.

The students who are graduating from IIT and have a CGPA of 8 or above out of 10, can get direct admission without appearing for GATE. And the students who are not from IIT should have to take 750-780 rank for securing a seat in any branch of IIT Kharagpur through GATE.

It depends on your branch. I think you cannot get a good NIT with this score.

Yes, you could get. Apply to local government colleges or NITs through CCMT portal.

For management related courses through GATE you could choose in IISC (Masters in Management) or NMIMS.
