Banaras Hindu University is one of the most sought after Universities in the country and for post gradudation courses especially in subjects like geology, the competition is very very tough. And the seats are equally less. 299 rank in obc category is very far away from the cut-off even considering the reservation of seats for this category. However 95 female rank under OBC category might get you a paid seat. You have to contact the University for better clarifications. It looks like you have a chance of getting a paid seat later.
