Hello applicant,
As far as I am concern if I you are able to score 80% in your first year then you can get another branch for second year.
But for colleges there are some protocols to follow .I believe that you should first contact to your college administration for the same.
Hope it helps.

Hello Sekhar ghosh,
According to the university the rules and regulations might change .
So according to your query about the changing the stream after first year depends on the management and the rules of the institute for further information you have to contact the administrator of the university
All the best
