<p>If I translated a very very lengthy manual over the summer, should I send that in as a supplement? Just to show that I did it? (Over 420 pgs.. )</p>
<p>No. Mention that you did it in your application, sure. But attaching 420 page documents will do nothing but get admissions workers very annoyed at you. And possibly cost them a lot, if they print out all their applications.</p>
