Hello Dear,

As you know, all the seats of WBJEE are allotted on the basis of GMR rank. It is very difficult to predict the college because you do not mention your state region. And your general merit rank is 30230. You are belonging to SC category. So you have SC category quota. There is a chance to get admission in GURU NANAK INSTITUTE OF TECHNOLOGY .

You can also predict college from the link given below :
