What's different about it is its circularity. The students' anticipations of the exam are based on their anticipations of the exam. Sort of like "this statement is false".

The students' anticipations of the exam are their anticipations of the exam. I don't see the circularity yet. It's clearer in the Liar Paradox.

Circularity is here:

    P( exam is today | P(exam is today | exam was not earlier) = 1) = 0
EDIT: if this is good formalisation of proffesor sentence. I'm not 100% sure.
