In CSAB rounds, you will be given NIT/IIIT according to your category rank if applicable, or else, General.

You can check the previous year's cutoff's at

Generally homestate NITs are easier to get than that of the other states. REGISTRATION FOR THE COUNSELLING HAS BEEN STARTED FROM TODAY AND WILL BE OPEN TILL 25 JUNE 2018. BEST OF LUCK!

On the basis of JEE main rank, you could get a seat in NITs and IIITs but not in IITs. You should visit
https://josaa.nic.in/josaaorcrarchieve/Result/OpeningClosingRankArchieveN.aspx?Year=2017
and check the previous year's cutoff's of your HOMESTATE NIT first and then the other NITs you want. There you would get an idea of your selection. ALSO, THE REGISTRATION FOR COUNSELLING HAS BEEN STARTED FROM TODAY AND WILL BE AVAILABLE UPTO 25 JUNE 2018. So take care of the important dates also. BEST OF LUCK!

Since NITs are tough, among NIT-Patna, Bhopal, Jaipur, Kozhikode and Calicut, try for each with only home state quota. Else, go for Private Universities offering B.Arch and B.Planning.

I would suggest you to again acknowledge your rank as it's not likely to have such a huge difference in the category and General Rankings. Moreover, till then, use our college predictor to better explore the opportunities:

Sorry, but all NIT admissions close down to at maximum All India rank of 60000 for freshers batch. Rest rankings are for assuring students, their seats in JEE Advanced. Also, for any NIT, the minimum rank required for CS/IT is 15000 all India. Kindly go for state government autonomous institutes with home state quotas or private universities.
Best of luck.

You may try for JoSAA counselling but it's quite difficult to find a seat in a government architecture institution as they close within 2000 for SC,ST or OBC category.
