You are right @halflokum. But other classes (including theater things like ITS, ITP, History of theater etc) are 3 credits = 3 hours. I just tend to think of “studio” as a chunk - she goes up to that building for the day, and I have NO idea which days are voice& speech, scene study, yada yada. She does spend more than 8 hours a week there - (a quick glance says she is in the building, attending class over 20 hours a week) So I stand corrected.
