Harvard's Upload Materials

<p>Hi, so I just applied to Harvard Early Action and on my application status it has a place where I can upload materials and the categories are "additional academic material", "non-academic material", and "miscellanous". Do you guys have any ideas what kinds of things I should upload? I might upload a resume and an outside recommendation, but I don't know what else. Also, does anyone know if we're only allowed to submit one or more than one?</p>

<p>I have a similar question and I was wondering if somebody can throw some light on it. Do I have to upload any documents, or only if I want to upload some research or something?</p>
