<p>^ Only one recommendation is required, but you can submit more if you feel the additional recommendations add something to your application.</p>
<p>If you print it out, you can mail it in with the sealed letters of recommendation. I would not advise opening the letters and scanning them, because then they would no longer be official. When the application becomes available, there may be a way to have your recommenders submit a recommendation directly to USC electronically (many schools have this available now), but you would have to wait for the online application to become available before you could use that. </p>
<p>As long as you include your USC ID# on everything you send it will be matched up. USC is very flexible about how you get the materials in - just get it to them somehow and they will match it up.</p>
