<p>When do supplements to the Common App usually come out?/Are they out yet? I've been looking for the Stanford/Upenn/UChicago ones, and couldn't find them on their websites.</p>
<p>Sometimes at the end of the summer - maybe August 1. Often, they are the same as the previous year, so it would be pretty safe to assume that as you work on them over the summer. August 1 is a common date, sometimes as late as September 1. Of course, you could email admissions departments and ask!</p>
