Loss of an exam day in a four-week class A friend of mine is a mathematics professor at a college in the southeast United States (where they're currently expecting significant snowfall) and just asked an interesting question that I'm reposting here:

I'm currently teaching a four-week class, and next week is the final week.  There is a good chance that the college will be closed Friday due to the weather, but Friday is also scheduled to be an exam day.
How should I handle this?  I cannot afford to use the last Monday as the new exam day.  My initial thought is that I could post it as take-home exam with strict warnings about using resources, but we can probably guess how well that will go.

I'm sure that she would appreciate any suggestions you might have, and I am also curious to see what they might be.
This is a college level issue. The school should come up with a plan for how such a problem should be handled. It seems absurd to ask each individual professor to come up with a specific plan for his/her own students.
