I do not have a comprehensive ranking of the sessions since I only watched a couple of the sessions over the shoulder of kid/listened while prepping dinner.
I have to compliment the Hill School on the fact that their Headmaster, Zach Lehman, was a fun moderator on at least a couple of their sessions. It certainly gave a personal touch and I feel like he’d know what was going on with every kid on campus. It gave credibility to the “Family Boarding School” motto.
