<p>Is there a supplemental essay required or do you just submit the Common App?</p>
<p>Go to <a href="http://www.washu.edu%5B/url%5D">www.washu.edu</a> and click Admissions. You'll get all the info you need and then some, including copies of the apps, instructions, etc. However, as I recall, Wash U has a pre-app data sheet and the Common App, then the usual school report, midyear report, and teacher evaluation forms and that's it. There is no supplemental essay, though you can submit supplemental material if you like. I did.</p>
