Hey Sonal, 

There are good chances for Spot Round to happen this year as the third round counselling has ended very soon on July 13th which presents enough time for them conduct spot round counselling to fill up all the vacant seats.

The dates for registration is expected to be released in first week of August Month. Be regular on JU's website to be updated about any notification regarding it. 

Good Luck! 

Maybe yes they have sport round in WBJEE in this year because of they may have last year. and maybe sport round has in all counselling so they are some chance that they may conduct sport round this year. So if they have you may soon get the notification or may be asked for main Counselling office.

all the best
