<p>Okay so for the activities part, I didn't put in an important activity which I am a leader of. It's National Honor Society. Anyways, I immediately sent a message to the schools I applied for and asked them to add it on to my application. I gave them my common app id..and other info about the activity. Do you think this might work? I'm deeply worried right now...</p>
<p>You can contact the common app to ask for a change in your submitted application</p>
<p>Yangliu, I didn’t know you could alter the information directly on the common app after I sent it. I’ll try e-mailing common app right away! Thanks!</p>
<p>Umm I’m pretty sure you can’t ask the common app to change it. They say that once you submit it you can’t make changes. You have to contact each college.</p>
