Don't worry about it, do you have dyslexia? Our middle daughter who has a Mensa level intelligence has dyslexia as does her younger son, but she still got her degree. Her lad, who is 16 next month, is going to study electrical engineering.
Although I have never been tested for it, I think I have dyscalculia, which is a problem with maths. I have never got to grips with the subject, even though I had maths tutors throughout my childhood. Thank goodness for calculators, or I would be really stuffed when checking our bank accounts as I do on a daily basis.
It used to worry me in the long distant past, it just get annoyed with myself now more than anything else.
It's irksome the spelling where I can't even get close enough for spell checker to know what I'm looking for.
I go to google for a lot of my stuff the spell checker wont pick up or, say a word begins with 'M' I'm looking for I then go to my O E D the shorter version start at the beginning of the m's and keep running through until I come to the word I'm looking for, fortunately I'm a really fast reader at least I've not had any significant trouble with that.
Oh yes I can be spelling a word without any trouble one day and have trouble with the same word the next day or time.
All this and my Mensa score is 275, difficult to believe I know.
Regards, ippy.
