<p>i just realized i made a mistake in the essay..i just left out one word...will that look bad and make me seem incompetent?</p>
<p>don't worry about it. anyway, there is nothing you can do now.</p>
<p>no.... people get way to worried over little mistakes! they will be reading what you have written with some speed anyway, so the likelyhood that they will actually notice is small, and even if you do, you will be one of many applicants to make a minor mistake!</p>
