Hello,

I don't understand in which grading system your results are published. I think it is O but you wrote it in mistake as p. It's just a guess.

This might be a serious problem. Go and meet to your administration department and ask them to correct it right away. They will take some time but they will do. Make sure that you really got some other grade as you mentioned in your question.

take a screenshot of it if possible and show them everything and explain them where it is done mistake. They will help you and correct it soon.

Hope it helps!
