My son was exactly the same as yours, but not considered dyslexic. ( This was some years ago, before dyslexia was as recognised as it is now.) Getting him to write was a nightmare, even after he chose to go to college. Sadly, although he finished his course, he didn't pass as his final thesis wasn't up to scratch. He carries all the information in his head, and a lot more besides, and after some years of working in dead-end jobs has now decided what to do with his life. He still doesn't like writing and I'm afraid he won't get as far as he is capable of as everything seems to hinge on exam passes and degrees.He did manage to get reasonable GCSE results, but it's such a shame that the world of work seems to rely so much on pieces of paper and not on competency and knowledge. I don't suppose I've been much help, but I worried like you and it got me nowhere and strained my relationship with my son as I was always nagging. Talk to your sons teacher, go for the dyslexia test and take it from there. Perhaps I should say that my son is very bright, eloquent, and well-rounded in every way - despite not liking to write.
