Can you change your college? I am also want to change..

It totally depends on college to college.

Every college have seperate policy.

You can write a application to your college regarding the change of the college. If they approve you can send that application to the college in which you want to take admission if  they approve you can change your college. 

It's totally depends on the college whether they will take full fees or will charge some amount. 

Good Luck!!
