Made a HUGE error on my penn app - please help?

<p>On the activities section of the common app, I accidentally put myself down as having down Science Olympiad for only 10th and 11th grade, but in actuality I'm ALSO planning on doing it 12th grade. This is a pretty HUGE EC for me, so I"m really freaking out. I already submitted the app. My resume, on the other hand, reflects the number of years accurately. Should I email penn just to clarify the mistake, or would that just annoy them. </p>

<p>Really begging for help on this one guys. Don't let me down...</p>

<p>Shoot your regional director an email, shouldn’t be too big of a problem.</p>
