<p>I did not submit it on Common App because the essay textbox can only take 1000 characters. Instead, I sumitted on Colby's own supplemental website. </p>
<p>After I clicked "Submit", I did not receive any confirmation. What should I do???!!!</p>
<p>Personally, I would e-mail the Colby admissions office and explain your concern. Even though they are being inundated with applications right now, they should be willing to help you out and ensure that your supplement reached them.</p>
