Dear Aspirant

I am afraid to tell you that if SC quota is not showing in registration page then you may not get  SC seat through counselling. During document verification in WBJEE counselling rounds one has to show one's particular category certificate as a proof . So if your registration page is not showing your SC category then during counselling you will not be offered any of the SC seats . This will be a serious problem of yours so you try to contact with WBJEEB board as  soon as possible.
