Hi Aditya

It's quite difficult to predict the marks required in BHU UET examination to get a seat for BSC biology group as it keeps changing every year depending upon various factors like number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc

But yes as per previous year trends to get into BHU for your BSc Biology group you should try to get at least 280 marks in your BHU UET examination.

For example,
In BHU UET examination 2018 , a general category student required 265 marks to get a seat in BHU for BSC bio group.
