Is it still worth it to show demonstrated interest even though I applied ED? - NEU

Help.
I applied to Northeastern ED and did several steps to show demonstrated interest including:
visiting the school, writing a supplemental about why NEU is my first step and adding it to the “additional information” section of the App Status, and have emailed the admissions counselor back and forth.

However, I just saw someone say that theres no point in showing demonstrated interest if you already did ED since you’re definitely going to attend if accepted. I never though of it this way and I feel like an idiot…

Is there ANY way my demonstrated interest could somehow help me or did I simply waste my time??? I am so frustrated.

Applying ED is he ultimate way to show interest. Your stats from your other thread definitely put you in the range. Visiting any college is a good idea not just to show interest but to get a feel for the school. Good luck!
