Hi Priti,

It is very difficult to predict the college because you do not mention your state region. All the seats of WBJEE are allotted on the basis of GMR rank. And your general rank is 30230 and also you are belonging to SC category. So you have SC category quota. There is chance to get admission in some good colleges for B.Pharma course such as

BCDA College Of Pharmacy and Technology

Bengal School Of Technology

Birbhum Pharmacy School

Brainware University, etc.

You can predict college from the link given below
