Hard to do. The parents snatched up ticket for their families some time ago. The crowd in the cheap seats will be all parents and family. And, the only thing that happens at the graduation other than speeches is the awarding of PhDs, a lot to Chinese and other foreign students.
No undergraduate names are read. They just have each department stand up. "English Department." Yay! "Chemistry Department." Yay! They don't even get their diplomas. That happens when they turn in their gowns after the 'ceremony.' It's really kind of anticlimactic. Sometimes parents can't even see their kid in the crowd.
The real graduations take place on the department level at an earlier time. The kids and their classmates get their names read and shake hands with the professors in the department. Everybody know everybody. Much nicer. AND, no pro-abortion, anti-capitalism President Ponzi.
Thanks. That is good to know.
