As there are lot of college which accept WBJEE score for admission.If you have domicile means you are local candidate then you don't need to worry so much as there are 75% seat reserved for local candidate.But If you are from other state,then You need rank under 2k to get government college through WBJEE under general quota.Even in rank of 81k candidate can take admission in government college like jadavpur with Metallurgy stream under general quota.

You can ask if you have any other queries.

GOOD LUCK!
