<p>For my additional information section, I decided to include an essay as to why I chose my major. Is this acceptable?</p>
<p>If you already submitted it, then thats fine, but if you haven’t, I would take it out. If they wanted an extra essay they would have asked for it. Likely they’ll probably just skim over it. Additional Information is more for explaining something like you got that D in chemistry 2nd semester because your sister got in a car crash and you had to miss the final, or for including something like “my uncle is an associate professor in the history department.” Extra essays usually just bog down a reader.</p>
