Hello Anupam

You need to check previous years' closing ranks inorder to ensure that you can get any seat in a government college of your preferred branch, i.e., ECE. Accordingly, you can get the following colleges for ECE-

Netaji Subhash Engineering College, Kolkata

BP Poddar Institute of Management and Technology, Kolkata

You can also refer to the college predictor link to get a better idea-https://www.careers360.com/wbjee-college-predictor

I hope this helps you. All the best!!
