DM was studying at SH in 1973, maybe 1974, I believe. That was when I got that ruds session from him. I thought he was on the Academy Levels. I don't know if he later routed onto the SHSBC.
I don't remember what the rules were for graduating the SHSBC, and they could indeed have been that skimpy. It is around the time of the disastrous "Conditional Cert" system for the Academy Levels, where you could graduate without any auditing and then you got to audit on an Internship.
But all this is not the same as being trained to deliver quickie grades, if anyone got that idea.
