Hii Archana!

This purely depends on the merit list, the number of candidates, and the intake capàcity of the College, whether you get admissions or not. If you are a permanent resident of West Bengal, you may get a benefit on admissions. Some of the Colleges in Kolkata offering b.com course are-

* St. Xavier's College

* Goenka college of Commerce and business administration

* Seth Anandaram Jaipuria College

* Deshbandhu College for girls

Etc.,

Hope this helps.

Good luck!
