When in school we did the RSGB exam during our after school science society sessions. I don't remember anyone taking it further though.
Much the same for myself. I attended a night school run by a maths teacher who started the schools radio club, being a radio ham himself. Beam tetrodes ruled in the syllabus, no semiconductors then, with the course culminating in the C & G radio amateurs exam which included a section on law. This taken and passed at the local tech college.
