You are writing to the Chair of the Liberal Arts Department at Seneca College. You can make up a name for the purposes of the assignment. Tone: Your tone should be professional and semi-formal. You are a student, so there is no need to be overly formal, but you do need to maintain a professional tone. No short forms, slang, contractions, or acronyms (unless they are explained). This information has been added to the assignment sheet itself, so you will see it there as well.
