"IF" you are truly an "instructor" as you say, would you not know the difference between "your" and "you're"? That is basic grammar. I question your statement that you have been an "instructor" for 7 years. If your (this is the PROPER use of this word) employer saw this basic grammatical error, they may question your qualifications as an "instructor." And I can assure you that I am a teacher at Ivy and Adam and I are two distinctly different individuals.
