YES!
The Dyslexia thing, I had it bad as a child, my teachers just thought I was slow, then I started catching up. It hasn't made my grammer or spelling anyworse, I just read very differently to most people. And now actually faster than most as I recognise the shape of a word instead of looking at individual letters. Sure I'll make spelling mistakes here and there, but I'm only human.
People who tell me they are dyslexic and use it as an excuse as to why they are getting terrible grades/failing a course really annoy me. If it really affects you so badly there are funds available for laptops (I can read typed script far easier than someones hand writing and have to write in uppercase myself) and also scribes. There is no reason for anyone to have it bring down grades or cause them to fail.
I'll also point out when you mention this to people with 'Dyslexia' they seem to refuse it as it means they'll have to be diagnosed by a proffesional. When the results come back that they are just thick they'll no longer have that excuse to use.
It proper grinds my gears if you couldn't tell by the length of this reply. I did once tell a girl i worked with who had informed me she was dyslexic after she didn't understand a sentence I had said, yes that's right one that I had spoken, I simply said "Chick I am dyslexic, you are just stupid".

Funnily enough
One of the ways mine presents is understanding verbal communication - I'm terrible with strong accents. One of my dad's colleague's is Egyptian and I cannot - no matter how hard I concentrate or try - understand him. I have watched my father have whole conversations with him and only understood my dad's side of it. Unfortuantely, much as I LOVE a Scottish accent, some are completely unintelligible to me :(

the girl in question was also Scottish and from the same region as me.#
our accents were the same.

Then she was quite clearly an idiot

indeed,
oh and it was the meaning of the sentence she was confused about, instead of just saying "you want me to do what sorry?" She played the D card.
