Hello aspirant,
Hope you are doing absolutely great.
So with regard to your query, NO, not at all, the Uttar Pradesh Open School Board (UPSOSB) is not a fake institution. It is an autonomous board recognized by the ministry of education in Uttar Pradesh state. It is also a general body in the National Institute of Open Schooling (NIOS).
Hope this helps you,
Good luck, Thank you.
