How I can so relate to this! Being dyslexic long before the condition was widely known my high IQ lay buried beneath totally incomprehensible spelling. Only after leaving school was I able to bring my mind to bare and learn how to overcome this becoming the only pupil from my poor secondary school to obtain a degree and go on to teach others.
One of the secrets of my success as a private tutor was my delight in unlocking the treasures buried in these brilliant minds and showing them how to apply them. Nothing can give more satisfaction to a teacher.
