Hello dear, yes there is some fair chances that you will get CS in Jadavpur , but you have to wait for last round of counselling. Additionally I have attached a link were you will find cutoff of previous year do check it for better idea.

And you can also use our WBJEE college predictor for complete accurate answer, and below you will get the link for that too.

You can see the opening and closing ranks of last year. That will give you avettet insight. But anyways, I guess , your rank has to be well within 1300–1400 to take admission in JU.

So getting a seat is a bit tough than you expect hope to have a second option. 

Thank you.
