<p>How do you simultaneously submit common app and supplement for northeastern?</p>
<p>I wonder why you are asking this. The sequence is: submit the supplement first, then the application. I submitted all four of my supplements, then about a week later I submitted the main application.</p>
<p>The website said to submit both “simultaneously”.</p>
<ol>
<li>Complete the Common Application and the required Nort supplement simultaneously, which you’ll access through the Read all application instructions carefully.</li>
</ol>

<p>Huh. That’s weird. Well, I can only say that I submitted my supplement on 9/16 and submitted the Common App (and payment) on 9/22. I got the application acknowledgment from Northeastern on 10/11 and there was no mention of a failure to submit the app/supplement in the correct order and everything on my application status page looks correct. So, I think the typical process on commonapp.org outweighs those instructions. Best of luck with your application!</p>
<p>Awesome, thanks. Good luck to you too!</p>
