Hello,

As per last year(2019) the cutoff for BHU UET for Bsc.(Hons) Maths group for ST ( M and F) was from rank 1-308.

So you have a good chance in getting the college according to the previous year trends but there can be a change in rank this year so nothing can be said for sure.

You may get a hostel too provided your parents are not residing 8kmfrom the university campus keeping in mind the vacancy status.You can copy paste and visit the official hostel manual

( https://www.bhu.ac.in/accommodation/HostelManual.pdf ) to get a detailed knowledge about the eligibility and how seats are alloted.

All the best!
