Is it worth it to add to my app that I organized a major fundraising event at my school for charity?

As president of my Cambodian-Thai Club my club and I are organizing a fundraising event at our large highschool of 4,000+ students and we are hoping for a goal of $5000-$6000 to a charity for Cambodian youth education.

Is it worth noting on my college app that I organized this?

sure! absolutely!
