One of my friends was a student of the IEM thus, he had his reasons to make a choice among all the given options which might help you choose a college for yourself. 

Instead of enrolling for any college under WBJEE, you can try to go for IITs. If you have no luck there, then you should opt for government colleges such as CU, JU, and KGEC.

Talking about IEM, you should know IEM provides a good opportunity for the students with all the favorable benefits. 

Apart from this, Heritage Institute of Technology is not a good choice as the crowd of students doesn’t have any standards. Most of them are enrolled by the management quota. You may also go to other colleges like Techno Main Saltlake otherwise, you can also choose GCETT Serampore, near Kolkata, as it is also a good college.
