Dear Aspirant,

I'm glad that you wish to improve your scores and take admission in BHU. I suggest that you should definitely improve your mathematics. You should prepare for mathematics thoroughly and try to get the maximum no. of marks you can. I will also suggest that you do well in all your compartment exams but give a little bit of extra attention and time to mathematics. I'm providing you with a link to help you prepare for your Mathematics exam:
