On friday afternoon in class, the Headmaster tells his students that next week, they are to have an unexpected exam. That is, there will be an exam but they don't know on which day it will occur. |

Also the teacher says you will have an unexpected exam... Like BB said now they know they will have an exam so it is not unexpected. What the teacher means at this moment you don't know when the exam will be. To say it cannot be on friday because on thursday they would know it would have to be on friday is not logic... (at the moment they are told they will have the exam) |

There are great truths and there are trivial truths. The opposite of a trivial truth is obviously false. The opposite of a great truth is also true.
