I got that, and I know how their calendar works.
I just know that students will be under immense family pressure to get home, and that's really tough if they have to be present for Wednesday finals. I also know that the university typically requires a class meeting during that scheduled time, although they'll never know if a class doesn't meet.
Therefore, I'm hoping that they're flexible and allow people to take these online so that a few thousand students aren't stuck with a "Planes, Trains, and Automobiles" scenario for their trip home.
