i dont kno specially for wbjee, but generally the board itself will publish thier own key, solutions etc. on their website. so u might wanna watch and wait on their site.

and if they snatched away the q paper frm u in the end... like most of them, then u r only hope is them 2 publish it.no outside sols available in that case like iit etc.

Thanks so much for giving link to check WBJEE Papres.
