College Updates Model UN

If I was recently awarded outstanding delegate at Model UN conference (Harvard MUN), would it be worth updating all my colleges of my award? Or is it not significant enough/ might annoy them to share with them?

if you applied somewhere ED/REA and haven’t already written a letter of continued interest, you could update that school in your email. other than that, i guess you could tell all the colleges you’re applying to, but i would double check with a guidance counselor to see if that’s a good idea

She said not to.

If it is your only activity and only award, I would contact the colleges.
