Common App

<p>I was filling out the self-reporting section for exams on the common app. I self reported all my AP scores i have taken until now, and entered the ones i plan to take by the end of this year. I then sent the school I am applying early decision to my official AP score report.... did I have to send the official score report for AP exams? or is self reporting enough?
I am also doing early action to another school, and the deadline is soon and I don't want to pay for another AP score report unless I have to. (the early action school I am applying to is UNC Chapel Hill). I did do research before I came here, and I could not find an answer to my question.... and YES i did look on the school's website. </p>
