Can you self-report test scores for your application to Elon, or do you have to send official test scores from the testing agency?
That is definitely a question that you should ask your rep about, I’m sure they’d be happy to answer. Plus, it establishes communication and demonstrates interest, which can never hurt 
From what I gather from the website, they expect your test scores to arrive separately from your online application, hence from the testing agency themselves.

I personally sent the official test scores from the testing agency. I believe that’s what most, if not all, students do, just because that’s the way schools truly know you got that score. It’s just the more formal way of doing it I guess.
Good luck with finishing your application! Hopefully we’ll be able to welcome you to the Elon family in the near future
