<p>If this is a mistake you made consistently throughout your essay, then admissions might notice that, look for other mistakes, and it could hurt.</p>
<p>If you only did it once, I wouldn’t worry about it – they know that people make little mistakes like that all the time.</p>
<p>^Erm, hate to break it to everyone above, but Brown students are actually perfect. Beautiful, well-dressed, clear skinned, gorgeous hair, flawless, detailed and inquisitive minds, and bastions of good moral character. Didn’t you know that every test we ever take is always a 100%, because we make NO mistakes? And our admissions officers are perfect too: they can scan an essay in 5 seconds, and know every intimate detail about you, your capabilities, and where you will end up in 10 years. That’s the exact reason BrownFML is filled with students saying things like “Today I was perfect. As always. MLIG”</p>
