Many universities give students who claim to have dyslexia time-and-a-half or double time on their exams. Some demand open book exams.
My husband has terrible dyslexia. I wish we'd known that sooner!! Heh heh...
This is only true if the students have a 504 plan. Certain teachers may offer this, but to be required to do it requires a 504, which the parent must provide testing documentation. This testing is done with the parent's (or parent's insurance company)'s money.
