<p>I have heard that you can submit multiple versions of the Common App, but how is this done? If I am submitting an extra letter of recommendation, is it best to send it directly to the admissions office on paper? How should this be sent and indicated that it is for my app?</p>
<p>Yes send it to the admissions office by mail. Just plainly state your name and city near the top margin. They’ll scan it and place it into your file.</p>
<p>Top margin of the envelope, or the letter?</p>
<p>I’d definitely say the letter itself. Envelopes would be too easily discarded, dontcha think?</p>
