If he can win much more matches when he talks arrogant stuff,go ahead!
Sometimes arrogance can push people to higher limit!
Dear,your result is really good compared with me.
In last semester I just wanted to dig a hole to die coz my gpa is too low.
This semester I hope I have a big change in exam,in test or projects I admit when I act harsh and demanding,the result is better.
Just some classmates dislike this style,but who cares?
