Adcoms can't change their words right?

<p>couple of days ago, I sent my dream school an email that I want to switch my app from RD to ED2.
Today they replied me and said they will switch it for me.
so now I am officially an early applicant right?
I am so nervous that they will soon say no again.
As long as I recieved the email from adcom, i am an early applicant for sure right ?:(</p>

<p>thank u!</p>

<p>I’m sure that’s sufficient. Adcoms don’t want to be known for going back on their word. If you’re really concerned, just make sure you keep the e-mail in which they agreed to your request.</p>
