What are the differences between people who have dyslexia, and people who have a hard time writing papers?

What are the differences between people who are bad at writing papers and people who have dyslexia?

• I have a friend who is dyslexic(he can barely read, write and spell, but is good at math, physics and chemistry) and he wants to go into engineering, but engineering has a lot of papers that engineers need to write, what are the chances of dyslexic people in engineering schools as well as in the engineering field in general. I am also worried that for him being an engineer, he needs to be able to write tech papers in his job. Will his disability affect his chances of being in engineering school as well as being an engineer? Also, what are the differences between dyslexic people and people who don't know how to write papers? I remember that some of the people in yahoo answers explain that dyslexia is different than people who are horrible at writing essays. What are the differences between dyslexia and people who can't write papers for their life(in other words, people who are bad at writing papers). Better yet, how do teachers tell if students have dyslexia?

• Answer:

  Dyslexia is where you have more issues spelling and reading, the words seem fuzzy in your mind. Writing bad essays is just their style of writting, some people are just more talented as arty.
