Hello Aspirant
Your Jee score is very low . There is no chances of getting  admission in Nit or IIIT . You can try for private college . Your board percentage is only for elligiblity criteria in Jee ,no benefit in rank or in  admission procedure . You can take admission in Techno India Kolkata , Kalyani University Kolkata , Heritage institute of technology .
For more college here I am giving you a link to predict college .

Thanks and regards

Getting a seat in the NIT's with this rank is impossible.
And I want to make one more thing clear with a rank around 200000 may be you may get government (semi-government) college somewhere (which is next to impossible) but surely it will be the worst one with a combination of the worst branches.
The best I can suggest is that go take admission in some decent private college where they have placements and good college life.
Hope you got the answer for the question you asked. Thank-you
