<p>I am almost ready to turn in my common app but I was wondering if I have to submit the supplement at the same time?</p>
<p>You don’t have to submit the supp at the same time, just by the deadline.</p>
<p>One school in particular, I believe it was Michigan, wanted the supplement sent before the common application. It actually made sense, since they probably want THEIR portion “in-house” before the main common application that goes out to multiple schools, just in case they never receive their supplements. There probably are instructions, from the specific (common app.) school that you are applying to, when you get ready to submit on-line.</p>
