Last year I spoke in front of about 75 people, including my HS Superintendent, Asst Superintendent , Director Of Technology, Principal, County Legislator, multiple heads of Departments at Northrop Grumman, Bethpage, and God knows who else as the featured student speaker at the Northrop Grumman - Bethpage High School HIP Commencement Ceremony. I know it's not college stuff, but I'd say this was an exceptional situation for a HSer and above that of what public speaking the average college student does.
It was quite an experience, adrenaline rushing, heart pumping. I give it up for people that do it well.
