Hello,

First of all it's expected that from this year onwards BHU too will conduct admission for its various courses through CUCET, as there will be a total of 41 central universities that will be participating from 2021, now official notification regarding this isn't released yet, so we don't have  detailed information for the same, but if we go through last year official notification for PET, it's clearly mentioned that candidates who want to pursue MA Economics should have  studied Economics in all the three years of graduation, and secured an aggregate of 50% which doesn't happen in your case, so you cannot pursue  MA Economics in BHU, you can go through the official notification of PET last year at http://bhuonline.in.s3.amazonaws.com/pdfs20/PET_BULLETIN_2020.pdf
