AudeSapere, as far as I can tell you nailed the format of the school back in the day. Man, the JWs have it easy now! The 10-second timing rule was what caused me the most duress, that and "extemporaneous speaking".
I recently took a yearlong meditation teacher training. They assigned a five-minute talk. We had to use the theme from a slip of paper drawn from a bowl, and we only had an hour to prepare. I was already so anxious, because it felt so horribly familiar, and then the teacher said that since there were so many students, that the five-minute mark was a "hard stop". I dissociated (PTSD). The teacher said he was waving his arms trying to get my attention, but I was just staring straight ahead.
I started the "school" when I was nine-- pre-1975. You are right, it's a "F'n, lying, child-hating cult."
Also, I think more and more elderly JWs are realizing it's bogus, and they are going to die, including my father-in-law. His wife died in February this year, and his doctor just put him on antidepressants. He doesn't even go to meetings any more, and he won't even invite the elders in for a "shepherding call".
