If the point of homework is to learn the subject, while tests assess your understanding of the subject, why do the homework if you already have a strong grasp on it as soon as the teacher explains it? If the point of doing homework is to keep you busy, there are better things to do with one's childhood. Unless the disability you're referring to is that they never learned how to struggle (because no struggle was offered)...
