Rank this activity! (EC tier 1-4)

Hi! Hope yall are well. :)

Dropping by to see if this activity would be considered a tier-one EC. My AP enviro class just finished our annual project called the National Biodiversity Teach-In. Essentially, we reach out to grassroots activists, scientists, representatives, etc., and ask them to present for a series of webinars. Everything is completely student-run, including social media posting and outreach. My job was a leadership position in the communications department, where I spearheaded outreach in and out of district. If definitely worked, our district sign-ups were very high this year! I also managed to get our biggest presenter yet this year, the WWF chief scientist and senior VP. When it came time for some of us to run the webinars in the district office, I asked questions about presentations and helped fill up the Q&A time. As I mentioned before, we have people watching from all over the US, and some from other countries! However, this is an assignment or project we have to do, so would it be considered an EC or would I have to add it under activities? I can add more info if you'd like. ANYWAY, let me know what you think! :) <3
