Hi Shivam Raj.
Are you talking about JEE Main? If yes, chance of you getting an NIT is very less, unless if your homestate is any of the north eastern state, where he cutoff for HS quota can go upto 600000. So, please check the cutoff of your homestate NIT, under your category. And, if that's not the case, you can try to get admission in any of the SFTIs, in the counselling held by CSAB.

Good Luck.
