Dear Sharmishtha,

WBJEE counselling mainly happens after the publication of WBJEE Rank card .First of all, you need to do registration for WBJEE counselling and lock your choices with preferences and then pay the counselling fees.

There will be two rounds for seat allotment ,you need to wait up to two rounds to get your preferable colleges according to your rank and seat intake capabilities.

After then, there will be a mop-up round. Only apply for this if you can't get allotment to your preferred college according to your rank.

Note: JEE Main candidates are also eligible for WBJEE counselling.
