<p>I just sent my Common App off to American, Amherst, Northwestern, and Williams. Two hours later, I notice that I listed "15 hours a week / 40 weeks a year" for an EC when I meant to say "5 hours a week / 40 weeks a year". It's a pretty big difference. Should I just contact each admissions office to make the correction?</p>
<p>Absolutely. That is a 300% exaggeration if you don't.</p>
<p>Oh, there's no question that I'm going to make the correction. I just wanted to make sure that it's okay that I make the correction after the application deadline, since the admissions offices don't re-open until January 2.</p>
<p>Yes, it's ok.</p>
