Dear Yatharth,

Policy to change the college varies from each other.

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

You can write a application to your college regarding your issue to change the college if they accept your application you can forward it to the college in which you want to take the admission.

It totally depends on the college whether they will take full fees or will take some amount as no college will bear the loss of one seat.

Make sure you have good grades in 1st year with good attendance. 

All the Best!!
