<p>I just noticed that I submitted the wrong common app version to my top choice!
What can I do to rectify this? Should I call the school and tell them to discard it? Should I then print out the right version and send it by mail?</p>
<p>Ouch! Yes, call the school. Ask them what to do. They will probably tell you to print out the correct application and send it. You don't really have any other options that I can see.</p>
