I have a friend with a son who is very bright but has a terrible time writing. She says everyone thinks he is lazy in class becasue he doesnt' want to do his work--but he's frustrated because he can't write what he is thinking. He's 11 and his work looks like a 7 year old wrote it. He is failing most of his classes. do they have special classes for this? should i tell her to have him tested? does anybody know? thank you for helping.
