Not to fret getdonewithgmat!

Normally after you submit your application, you receive a confirmation and are assigned to an admissions officer who handles your file. Have you heard back from anyone yet? If so, I would definitely reach out to your officer directly and tell them you made a mistake and would like to submit your revised resume and they will attach it to your file. If you haven't heard from an officer, I would email the general admissions inbox anyways and let them know you'd like to submit a new resume. The good news is this seems quite minor to me and won't make or break your application so not to worry - I'm sure everything will be fine!

Best,

Thanks for the advice Melissa, appreciate it.

I was anxious and didn't want to leave it to chance, so I sent them the email explaining the error a few minutes after my initial post! It's good to know that it was the right way to approach it.

I hope that they don't consider it a negative.

Many thanks
