Hi Vishnu Prasad,

Permitting change of branch within the college during second year is decided by the college authorities.

You need to submit an application to the department head (the branch that you are willing to join). Based on the number of applicants and their performance in First year of study HoD will allow the vacant seats. This needs to be approved by the Principal and later should be informed to administrative department as the USN needs to be changed.

Yes you can change. But you have pass the first year without any backlog.
