<p>Yes, I was going to give the same advice as momof2 – just send a short email to the admissions officer for your area. Something like,</p>
<p>‘I wanted to offer a correction to one item on my common application. The extra curricular item “blah, blah” was incorrectly marked as summer after 11th grade, when it should have been summer after 10th grade.

I am very excited about my application to <college x=""> and am looking forward to receiving my admissions decision. Please contact me if you have any questions. Thanks! yetanotherid’</college></p>
