Hi 

as per the information, last year some departments in Banaras Hindu University had an intake of candidates who ranked even a little beyond 500 but they were of course called after the first and second round of counselling. 499 is a very far away rank in unreserved General category and 149 is comparatively a better rank for female colleges under BHU. You can wait till this month for your call letter from BHU but I suggest you to look for other colleges as well in the mean time.
