Hello.

Jadavpur University,  among many other colleges in West Bengal allow the students to change streams after their first year in B.Tech program. For this, you need to obtain a GPA high enough. It also depends upon the vacancy of the stream that you wish to change to.
For instance, a student studying Civil engineering can change to CSE after completion of UG-1 (1st year) if their GPA is higher than let's say, 8.5. And if CSE stream has any other vacancy left, you will be allowed to.

Hope this helps.

Dear aspirant,

Yes,you can change your branch after first year.

But your marks should be high so that you don't have to face problem in Changing the stream.

“We will allow students to apply for a change of stream when they move to the second year. This will depend on the marks they get in the first year and the vacancy in their stream of choice. So, if a student is studying mechanical engineering in the first year and wants to move to electronics in the second year, he or she will be able to do that provided there is a vacancy in electronics and the student scores more than other applicants.”
