College Admission Officers! I messed up on my Essay!!!

<p>1) So on a supplement essay, which i tweaked many times to use for many schools, i wrote the same sentence twice...</p>

<p>So.. this is the part of my essay.
"The applications for military and commercial uses were endless. I spent the summer collecting data and testing their product. I spent the summer collecting data and testing their product. I would..."</p>

<p>Would this affect the admission decision?
I messed up while revising and didn't check after the final revision ( i usually copy&paste it onto a different page and work on each paragraph and copy&paste back)
You may say i'm worrying over nothing, but i am still greatly worried.</p>

<p>2) Also, on my commonApp essay, i left out a period.
It is relatively a miniscule error compared to the first one, but i'm still worried.</p>

<p>3) On commonapp short essay section where it tells you to "elaborate on your extracurricular activity", I misunderstood the prompt and simply talked about music in general ...</p>

<p>Someone please tell me how much these factors matter!</p>

<p>None of those matter much at all. Admissions officers understand that typos happen. As for misunderstanding the prompt, they really just want to know more about you.</p>

<p>Don’t worry about it. Nothing you can do. Minor mistakes. They’ll take note but it won’t be the deciding factor or anything.</p>
