Hello Shivam, I have checked each and every NIT cutoff from NIT Warangal to NIT Agartala, I don't think you will get admission in B.Arch in any of the NITs because the closing ranks were a lower than your JEE rank. I would suggest you go through this JOSAA 2018 last round closing ranks for different IITs, NITs, and other government engineering colleges accepting JEE score: https://josaa.nic.in/webinfocms/Handler/FileHandler.ashx?i=File&ii=139&iii=Y . But I would honestly suggest you apply for private colleges if you can afford it and if you are really interested in engineering.
