One question about common app supplement!

<p>I am applying six schools through common app, and all of those school have their own supplements. Do I HAVE to submit supplements by deadline? or I just need to submit actual application by deadline and submit supplements later...
Schools that I am applying: Stanford, Washington U in St.Louis, Rice, Vanderbilt, Lehigh, U of Virginia</p>

<p>Thanks!</p>

<p>Applications and supplements have to be submitted by the deadline. In fact, in most cases you’ll find that commonapp.org won’t allow you to submit your application to a college until you’ve submitted that college’s supplement.</p>
