I'm a bit confused here...

<p>I have a question about submitting supplemental material to the University of Chicago.</p>

<p>It says on their website that:</p>

<p>To submit supporting materials for music, theater and dance, or visual arts and film, use the Arts Supplement form from the Common Application. You may also submit an additional recommendation from anyone who knows you well (e.g., coach, music or foreign language teacher, member of your community). Please use the Teacher Evaluation form in the Common Application for this purpose. You cannot submit this online; the person writing the recommendation must mail or fax us the forms.</p>

<p>Does this mean that all supplemental material (including CDs, teacher rec, etc.) have to be mailed? Or is it just the additional recommendation that has to be mailed by the teacher?</p>
