NIT

I really don't know any college in India which got a donation over 350 crores for a research Hospital by an alumnus. Every corner of the globe we are the ones to hold top managerial positions in various industries. Its true once our college was amongst the best 5 in our country until politics in West Bengal destroyed our legacy but we have the same zeal that kept Bengal Engineering College at the top. NIRF-MHRD ranked IIEST Shibpur 20, some rankings show 15,13 so on but come here and see for yourself why people who pass out this Institute somehow end up being the best in their fields.

If you belong to state boards, then chances are there. For that you have to see the different state boards cutoff. But if you belong to CBSE, then you are not eligible for getting admission through josaa.

It is very hard to get NIT even in eastern part NIT.

Maybe, you can get in eastern side NITs. Apply for those nits, some chances are there.

You have to do the choice fill-up at JOSAA website after registering with JOSAA. You can put as much college as you want according to your preference. Then after that cutoff will come and according to your rank, you will get the colleges. But make sure that you can't change the preference order after the cutoff or 1st round. After getting college, you have to visit the near NIT for getting enrolled in that college.

Hello, Hope you are doing well. As you said you have 69000 rank in JEE Mains so you can definitely get any government college with this marks but there will be problem in getting NIT because it requires more number and good rank. 69K is also a good rank but not for NIT only for government. All The Best.

Hello, Hope you are doing well. Sorry you will not be able to get the NIT with the marks 53 only because it's too less and you need almost ranks around 20K ( approximately ) which is not yours. Try to get some private college and go for councelling. All The Best.
