Hello aspirant!  Let me to inform you that till now there has been no such procedures of branch changing in jadavpur university after first year like some of the other colleges. Yes there was an article regarding this in times of India but till now there has been no official notice regarding this. Any change would be informed to you by the college administration so you must contact them.

There is a  good news for you.

The branch change is approved by Jadavpur University.

Son dont worry about it.

You can change branch by working hard and getting high CGPA

Very less students are allowed to change the branch

So aim for 9.6 CGPA and above Atleast for cse branch
