Dear Gunjan,

It totally depends on the colleges whether they will allow you to change the college.

According, to careers 360 BVUCOEP has AAAA ratings which means very good.

You can write a application to your college regarding th same if they accept your request you can forward your application to the college in which you want to take admission.

It totally depends on the college whether they will charge full fees or some amount if you leave the colleges as no college will bear a loss of one seat.

Good luck!!
