Hey Abhishek,

With the general rank of 1985 and OBC rank of 815, yes you are likely to get the admission in the BHU. Last year, the cut off rank in the B.Sc bio group was around 2300 and in maths group it was around 1700-1800. Even in the B.A courses the cut off rank was as high as 1890 in few courses. So, you are likely to get admission, if you have have chosen any of the course mentioned above. Hope this helps, thank you for asking question here at careers360.
