It’s amusing that you stopped here without giving an actual solution. Please do tell us, which day is the test on?
- mcphage 1y agoIt could be on any day—even the last—and would be a surprise.
- munchler 1y agoReally? Kids show up on the last day and know with certainty that the test is coming that day.
- mcphage 1y agoNot if they consider “we won’t have the test at all” as a possibility.
- munchler 1y agoWhat if the teacher writes the test day on a piece of paper at the beginning of the week and hides it in his desk? That way "we won't have the test at all" is no longer a possibility.
- mcphage 1y agoI think that gets you back to impossible instructions—if the teacher had written "Friday", then on Friday the students wouldn't be surprised by the test on Friday. I guess, unless the students think it's possible the teacher left it blank or wrote "No Test This Week" or something on it?
