I did not realize that I was supposed to submit UPenn's supplemental when I submitted my application. I mistakenly read their instructions wrong and thought that I was supposed to do it after my application has been mailed (which it still hasn't been - hopefully this week). Although I submitted 07/16, my GPA was just verified today due to a transcript mistake that my undergrad university made. It has now been about 6 weeks since I submitted and my supplemental is not done. I could probably have it finished by tomorrow morning and express ship it, but I am worried that I just totally screwed myself over.
