Slight error in my caltech supplement essay, what to do?

<p>In my caltech supplement I put then instead of than. Should I let them know or should I just let it go?</p>

<p>I honestly think you should just withdraw your app.
They don’t want a @#(@ing moron like you in their school.</p>

<p>^lol not cool. </p>

<p>yoskis- i’m not sure whether this post was a joke or not, but it is really not that serious.</p>

<p>Don’t let them know. It makes you look like someone who freaks out about stuff, which is a lot worse than someone who makes typos in their essays.</p>

<p>They are reading the applications so fast that they won’t even notice. And if they do notice, they won’t care. Everyone makes mistakes.</p>
