<p>It says on the app that this is only for "abnormally advanced" work and is completely optional...whats the deal?</p>
<p>If you have “abnormally advanced” skill in a certain area (research, art, music, etc.), then you can send in a supplemental sample of your work. If your skill is just average, you shouldn’t bother sending in extra materials.</p>
<p>However, the actual Harvard supplement that goes with the application is required of everyone. Last year, there were questions about the languages you know and your possible majors. There is also an area for an optional essay.</p>
