Like Esther said, we can't give you a "right" answer.
But, these characteristics are very common in children with ADD. I have also found kids with various Learning Disabilities also have many of these behaviors. the phrase "boring and stupid" almost always mean the student really does not know how to do the work or feels inadequate (LD kids often have poor social skills). This is a self-defense or survival behavior. It is safer for a kid to refuse to do an assignment and be called lazy or stubborn, than to do it wrong and be called stupid.
