Hello , 

As your query is you want to opt for Chemical Engineering at Jadavpur University and you eventually don't like chemistry. 

I would like to tell you that , your query answered what you seek for for. In the four years of Chemical Engineering at will be all about chemistry and various other stuffs related to chemistry only. I would like to tell you that since you don't like chemistry then these upcoming fours years would be only a hard challenge for you and that will end up wasting your whole career , therefore the college doesn't matter. 

Your choice and way of interest matters the most. Further, if you have any other query regarding the same you can let me know in the comment section below.

I hope your query is solved.

Thank you.
