Hello aspirant

Usually colleges don't allow a student to change their college in between the course but they do allow some exceptions if you really have a strong reason to do so. Also there's usually criteria if you want to get admission in a college, i.e your marks will be considered along with your behavior. Also you will have to get the transfer certificate but this process is very tideous and not every college authority allows this. So i would suggest you talk to your present college authorities and contact the college authorities where you want to go and if both the authorities are ready to help you change then go ahead.

If you really need to change the college then you can also repeat your first year by filling the applications form once again.

Hope this helps
