In my opinion, I'd say that the videos give an overview, but it's definitely too scripted. The best thing is definitely a visit to the school. True, the students are all amazing like the video, but there's a difference. You get a feel for the school. Like Hotchkiss seemed perfect for me on the website...but for me (and again for ME, not others) I hated it when I went there. It was too "woodsy" and too far off from other places for me. I like Exeter because it's nestled into a little town, but it's still walking distance to town.
Just my thoughts.
