Teacher uploaded the wrong letter of recommendation and I already submitted my application?

Hello,
So I submitted my applications for Emory, Brown, Vanderbilt, and Columbia today. The problem is, a few hours after I submitted them, I got a call from my teacher and she says that she uploaded the letter for another student. I told her the names of the schools that I would need her to call. She said that she would take care of it but is there something that I should do? I just want to make sure that all of my schools are getting the correct letters. I am considering calling the admissions offices of each school to make sure. Would this be a good idea?
Thanks a ton

You can call or email admissions to make sure that they have the correct letter or ask your guidance counselor to do so.

Okay, thank you, I will do that

I appreciate the help
