Nur's English Mark

I have a cousin, her name is Nur. She had an English test yesterday. The questions were very difficult, but she thought she could answer all the question. Because she had studied hard before the English test, she believed she could. She gave the result. Hopefully, she got excellent mark. She got 10, so she felt very happy. But she was not arogant because of her good mark. She was lucky, for some her classmates didn't got good mark.
