It would have helped if anyone had known I'm dyslexic and a bit ADHA.
Anyway, I got to Grammar school... to the surprise of all.
There I proved to be a dismal linguist, but quite a good scientist, essentially I did well in the subjects that were well taught, but I got board rather easily.
Managed 3 acceptable A Levels, it would have been better but I didn't really concentrate: for example my chemistry report in the Lower 6th was "Jenks would do better if he followed our syllabus and not his own"...
I could have gone to a good University, but instead I got into Brunel through the clearing system.
4 years I emerged with a 2nd class (upper division) Honours degree in Applied Biochemistry.
46 years later it seems to have served me well enough. I still feel a bit sorry for the teachers who couldn't understand why I tended to be disruptive, unfocussed and prone to focus on what interested me. Now of course I'd be in the hands of the educational psychologists and special needs: would it have helped me? I'm not sure.
