Problem with supplement

<p>I accidentally clicked on the bubble for a question listed under "outside the US and Canada." I answered that I had not the scheduled an interview, not realizing that the question did not apply to US citizens. But now I can't get rid of it. I can change my answer, but I can't choose to not answer. I've tried removing Harvard from my list of colleges and then adding it again, hoping to start over, but it comes back with all the answers intact. For something seemingly so insignificant, this is getting frustrating. Does anyone know how I can change it?</p>

<p>If you leave it blank, they’ll probably get the idea.</p>
