My son was dyslexic but I was not aware of it until after his studying years. Forturnately I gave him personal coaching and had to always monitor his work. To my surprise he did well in PMR and SPM. In his growing years he was always good in fixing things and always knew how to get something working. Now an adult doing well in automobile industry. Just know it is a struggle for them and pushing won't help. Challenging them little by little. Focus on all their strengths rather then their limitations.
