Well you'll never be taken seriously if you can't maintain at least a minimum standard of decent English - as it stands you appear to be about 8 or 9 years old (and doing poorly in English).
You have not been to the US lately. For my age I have fairly good grammar compared to some of my friends. 8 or 9 years old.....that's like 3rd grade. I learned to read in second grade. And I have comprehension problems. I can get test read to me. I also get extra time for tests. Are school does take special ed. very seriously.
