Heritage institute of technology if one of the best private Colleges of West Bengal. Placement is very good there but just for CS/IT branch.Other branches has average placement.

Amity is one of the good colleges in Kolkata. Apart from Amity, you can also go for Xavier's which is the best for management studies.

I think they might not as it's a state board examination and you have to get the certificate from the state from where you stay. But still you can better try to contact with WBJEE board through phone call/e-mail to get the most right answer in this connection.
