Hi

Extremely sorry but Uttar Pradesh State Open School Board is not valid anywhere.

This is because,

It's not a recognised board

It's a fake board.

It even made a headline once in Hindustan times.

Anyway,

You can get the complete list of valid and recognised board on the official website of council of boards of school education, the link of the same is given below:-

( copy the link and search)

Regards

Thankyou
