Mistakes on my essays

<p>do colleges throw your applications right away if they see spelling or grammar mistakes? i think i made some and didn't realize that until i submitted the essays. </p>

<p>for example,
writing 3rd instead of spelling that out</p>

<p>I have a similar problem. In one sentence, I admitted a "was", which is considerably word than a "3rd" (I imagine this may even be acceptable given character constraints). Would it truly be necessary to ask to fax/submit a new document to the school? Would they throw it out?</p>
