<p>How much of a difference will it make?</p>
<p>My typo was on my personal statement and went something like this:</p>
<p>CORRECT: My brother is an active volunteer at school.</p>
<p>MY TYPO: My brother is an active volunteerS at school.</p>
<p>I hope this is a joke.</p>
<p>It will not likely have any material effect.</p>
<p>No it actually isn’t a joke. I hope I did not perceive it as such. I am actually a very paranoid person especially academically so when I saw this it freaked me out. 
I am glad I got some reassurance from you too! Especially Silverturtle the high score baller on the SAT</p>
<p>Well then, it won’t change anything. The admissions people know small mistakes happen from time to time and they don’t discount years of your school work and learning because of that. UCSD sent out acceptance letters to all the kids they meant to reject last year, so see, they definitely make mistakes too and can understand when other people make them.</p>
