Typo in my Essay??

So I just submitted to my dream school and I think its a pretty decent essay. I have edited and improved it about 5 times. I was reading over my submission and in one spot it says hi instead of his!!!
I’m freaking out. Do you think this will affect my chances? Or do you think they will overlook it because it was obviously just something I didn’t catch and everyone knows how to spell “his”?
Please let me know what you think!
Thanks!!

also on one of the supplement questions specific to that school I said “getting a graduate school” (cringe)
But i think all my writing submissions to that school have good content.

I won’t worry about it too much. My son was accepted into Columbia with a small typo in one of the many essays they ask for. His essays were amazing, he had unbelievable EC’s and his stats were on par so one small typo was not the end of the world. If you were meant to go to your “dream” school you will get in even with one small typo.
