All the students, who scored above in wbjee, are provided with GMR(general merit rank).There are number of reservations for OBC/SC/ST candidates and also for meritorious and financially weaker candidates (in the form of TFW, available for all categories).All these quotas are available for West Bengal students.For, other state students, there is no specific quota.All of them are considered in general category,therefore there GMR is considered during admission.

Hi Azad Mondal,

Your Quota rank is required for couselling. You can even see the prev year cutoff ranks for OBC-A candidates on this link: https://engineering.careers360.com/articles/wbjee-cutoff.
