Mr. Koontz is a smart man who knows what he is doing. for those who say that he can't teach you are wrong. he wants his students to take the initiative and ask him questions.
mr. koontz cannot teach physics to save his life. He shows us videos of a professor who is teaching his class and that is how we are supposed to learn the chapter.
he is friendly he is funny he knows what he is talking about he is willing to explain things when i am confused
