I have been teaching organic chemistry for years. The subject is difficult, of course, for students to teach it hard, and not hurt hunting for many. And in order not to learn, they prefer to write from each other. Here and at the last exam, I observed in detail how two guilds did this. I checked their work - both wrote absolute nonsense, but almost identical nonsense. It was necessary, of course, to put both pairs at once, but I decided to have fun - one put a pair and the other put a four.

The result did not make himself wait, the "double" ran to me in the office with the demands, say, he and his comrade have the same answers, and he does not understand why he got two, and his comrade four.

I pretended to be surprised and asked them both to come to me for a check. They got mad, they went in. I, like, over-checked the exams, thanked both for their honesty, and the "fourth" rating was also over-checked by two.

And then I the view from the window, as they shouted to each other, and fisted their fists.
