Hi,

For applying to the M.Sc chemistry program at Banaras Hindu University a candidate need to have studied  chemistry in all the three years of B.Sc. To take admission in M.Sc chemistry at B.H.U math is not a compulsory subject.

as according to the guidelines of B.H.U

"B.Sc. (Hons.)/ B.Sc. under at least 10+2+3 pattern securing a minimum of 50% marks in the aggregate in Science subjects (considering all the three years of B.Sc. Course)."

So you are eligible to apply for M.Sc chemistry course at B.H.U.

Hope this helps.
