Résumé Common App Question

In Cornell’s supplement, they ask you if you want to upload a resume. What do they mean by that? I have already filled out the activities section in the common app. Will not uploading a resume hurt me? Even if I did upload one, what would I put on it that’s not listed in my activities section in the Common App?

There’s no need for an extra resume if you already filled out the activities sheet

No, it absolutely will not hurt you. In most cases it would be redundant and totally unnecessary.
