MA/PhD full time is all afternoon/evening classes, usually one day a week per class. I don’t think we ever started before 1pm, though it was typically closer to a 3-6pm/6-9pm schedule. The idea was we’d do our assistantships and teach the undergrad courses in the mornings (8-10ams) and have the world’s most inconvenient office hours in the space after that (between 11-2ish).
