Hey Premanshu

With a rank of 4953 in WBJEE even with obc quota your chances of getting a seat in a core subject(mechanical, civil, electrical and chemical) in Jadavpur University is not that high. The cutoff for Civil is around 3200 , for chemical it is around 2700 , for electrical it is 1075 and for mechanical it is 1815 for OBC category. Even with a category rank of 230 it will be really difficult for you to get admission in these streams. The cutoff for CSE,IT etc are even higher.

However you may get a seat in Kalyani in the core subjects! All the best!
