Dear candidate,

Still there is no official announcement regarding the WBJEE Mop-Up round so no one can say when Mop-Up round will begin.

So let us be patient and wait till they declare. To get updates tcheck official website regularly i.e

https://wbjeeb.nic.in/WBJEEBCouns/result/ResultIndex.aspx

It usually conducted at the end of July or after a few days of the last round of counseling.

Hope I answer your question and it's helpful.

All the best.
