I'm sure Mark knows what he's talking about, but I've heard medical personnel using dyslexia for all kinds of mixups, i.e. direction-dyslexic, numbers-dyslexic, etc. So if those things aren't really dyslexia, is there some other name for them. I find measuring impossible, as well as interchanging letters, have to serrupticiously "write" with my left hand (being lefthanded) in order to tell left from right, have albsolutely no sense of direction, and can't hold even two or three numbers in my head, as in repreating a telephone number, or adding up a column of figures. It's a minor inconvenience at best, now that I've had so many years to get used to it.

By the way, Mark, how did you get on with the Exam?
