Hey sourav,
As you have not mentioned any University here about which you want to get details of, i would assume you are asking for BHU? If that's not the case please, do let me know. So, coming back to your question, given by the past cut offs in the BHU for the MA in political science, i don't think it will be possible for you to get admission with 257 OBC rank, however cut offs change every year, so you never know, hope for the best. Hope this helps, thank you for asking question here at careers360.
