The other day, I assigned my students to prepare some cheating sheets as homework.
At first, as you can imagine, they looked at me in a high surprise, later they were delighted when I explained that they not only had to do that, but also we were going to have a contest and so the winner would have a prize.
I have to say that some of them, suspiciously, showed to be experts, it was quite difficult to decide on the winner.
But the good point is that some students told me, without asking, that they seriously took time to prepare the sheet and "surprinsingly" had learnt a lot. "Really?";)
OK, here you have the result of such hard work.
