Computer Science and Engineering in Haldia

You might get Haldia. IEM's closing rank for all the streams is generally much higher. I am not sure about Heritage. Put your preferences accordingly and hope for the best.

Hello Shubham,
As per your college choices, it will be better for you to move forward with CSE at Sant Longowal because colleges in Kolkata are not very much known for their exposure and placements, so opt for Longowal for better exposure and placements.
All the best!
