Goodness, for an "on-line" generation, something so simple is turning out to be complex.
I have a hybrid class. It meets together on Monday, then half the class comes on Wednesday and the other half on Thursday.
They can register for MW or MTh -- with the "on-line day" being the other.
Several bozos so far have insisted they registered for one, when they actually registered for the other.
At first I thought the software that pulls the class lists was off -- it's not beyond possible.
It turns out the students are off.
The problem is that I made some class deadlines different for the MW vs. MTh students.
I'm not doing that again -- now, thanks to this bunch of bozos, every hybrid in the future will have the same set of deadlines -- whatever the earlier ones are.
