For me, it was also the most unfair quiz.
In 9th grade literature, our teacher made a quiz about the different types of rhyme and those words like alliteratio, assonance and whatever. There were 8 multiple choice questions, 3 choices each. And in all of them, there were 2 choices that looked so good but didn't, just barely didn't fit question. One was slightly better than the other though. And he also phrased the questions like "Which of these 3 ..."
It turns out that if you wrote your name then left the entire quiz blank, you would have aced it. Literally everyone except for 2 people failed, one of them being absent that day so she got an automatic 100%, the other just gave up after 2 questions.
He even laughed at us the next day, making it seem like it was all a joke, but then said we should have known if they worked or not, and put them into our grade. Good thing it's only a small percent of the average.
