Hi

This is difficult to say as cut off depends upon various factors like :-

-----------) number of students/ candidates  that appeared in the BHU UET exam,

-----------) number of available seats,

-----------) performance of different students in BHU UET

-----------) the category you belong etc.

-----------) your marks/rank in BHU UET etc

But yes,

When we go through previous year trend then

You should target at least around 180 marks in order to get bhu bsc maths if you are from general category.

For example,

In 2018, the lowest marks that got admission for bsc maths group was 173 marks for general category.

2018 cut off is given below for your reference,
