Three hours projecting through a mask to 10 students spread through a 55 seat classroom (and a far-field microphone for all the others online) takes a toll on the vocal chords.
(If I may brag, we had a super first day. And there is no cohort more psyched up than MBAs in their first week of the program. But WOW: Hybrid is going to be so much harder pedagogically than straight-up online or F2F.)
