The Global Open University Nagaland — Fake Marksheets

Actually, I took admission in Hotel Management College under the Name of AIHM Noida, sector 65 near mamora chowk, They provide me the marksheets of this university where 1st and 2nd semester's marksheets are of the same month and year which is June 2019. I took admission in June 2018 and first semester was held at the college in December 2018 and second semester was held in June 2019 so how it's possible that me and my all friends got the both marksheets of the same year and month. First I was thinking that it's little mistake but when asked by my friends I feel that marksheets are fake. I want to know that is there any affiliation of AIHM Noida By your university or not, and the marksheets they provided us is genuine or not. I don't have more money to spend on Verifivations an all kindly provide me the answers please.
Roll no mentioned on the marksheet is- BHMTT-63/2018J
