Hi Kundan,
No, you can't get any nits or government colleges with this score in JEE Mains. Better if you go for state private colleges of West Bengal, Karnataka, Maharashtra, Madhya Pradesh etc. Or go for Amity, LPU, Galgotia, Sharda University, etc.
Best of luck.

Hi Soumyajit,
As your rank is low, so it will be better if you go for private colleges of West Bengal, Karnataka, Maharashtra, Gujarat, Madhya Pradesh etc. In west Bengal, you can go for Techno India, Haldia, Heritage, IIEST Shibpur, etc. for Bachelor of architecture courses.
Best of luck.

You have no chances in any NIT at this rank. You should rather try for private colleges.

You gave no chance in NIT Patna at this rank even in OBC category.

You just need to pass in all the subjects of class 12th board exams. If you score 60%+ then it will be helpful for you at the time of placement. You just need a valid score (above 40%) to get admission in NITs for Bachelor of Architecture courses.

It's not possible for you to get admission in IITs or NITs.
