Can I take chemical engineering at jadavpur university if I dislike chemistry?
Engineering branches are a very important decision and if you dislike them you'll end up living four most important years of your life in hating what you are doing every day. This will be a very exhausting experience and I would not recommend this. If you do not like something and you already know it then why are you going to join such a thing.
I suggest if you are forced to do this, then you talk to your parents, make them understand that you do not like this and wanted to do something else. Choose other branches like Electrical, Electronics and Communication, Computer Science or information technology.
You will not find any bit of chemistry in these branches.
Hope this helps.
