M.O.
I went there in the 70s-80s from kindergarten to 8th grade and loved every minute of it. My brother also went there for many years. I never went to another grammar school so I didn't know any different than the pod layout. I don't remember it feeling too big or chaotic. I found it to be a great school, I did very well there, and I remember the majority of teachers were really good, some were even inspiring.
But I don't know how it is these days.
