By the way, I have another one. In my country, you're supposed to attend high school when you're 13 and graduate at 17. And we have moral studies, which is one of the pointless subject ever along with gender studies. It was boring but not really torturing the first three years. You're supposed to memorize the 36 values (it may have been more or less than this number, I forgot) like believe in God and freedom of speech. During the exam, you're to apply the values in the situations given. It was so repititive if we had to study this in university, it would have been a one-off subject that students have to study for a semester and just forget about it altogether after the semester's over. But I digress.
It started to turn bad during the fourth year of my high school. Enters Mr I. Now this guy's kind of overweight, I think he and our equally obese principal are to reason the school didn't push healthy eating as much as other schools do. Anyway, Mr I couldn't be bothered to teach us the pointless subject. He told us that we should start to be indipendent now that we're fourth years or some shit like that, I don't exactly remember what he said. The point is, he wants us to form groups of four members each (shrunk to two during the fifth and final years) and do presentations to the class by writing the values on large pieces of paper.
Every time, and it's literally every time, mind you, one of the group is done with their presentation, he would be all sarcastic and tell them that they did a good job and told the rest of us to applause. After that, he'll start to berate them for all the mistakes they did sternly. As far as I remember, he was never satisfied with any of the presentations. Maybe it's because he has a weirdly high standard for a subject that his students could care less about.
One time, the format for our exam has changed all of a sudden, and the whole class and the class next to ours who also has Mr I as their moral teacher got low marks. As you might have imagined, Mr I blew his top. We could hear him yelling at our neighbour class, since they had moral studies one day before us. And on the next day, it was our turn.
Honestly, he's not a bad teacher. I'ts just that he took a pointless subject way too seriously.
