One day in high school we had a substitute teacher. At the beginning of class, the substitute teacher handed out a quiz and told us we'd be tested on it at the end of the period. During class, we searched the textbook in small groups to find the answers.
Unfortunately, some of us studied to pass the quiz instead of to learn. Rather than learning the material, we memorized the multiple-choice number sequence. And I "succeeded" — brilliantly. So brilliantly that I could ace that same quiz decades later. Yet, I don't remember the information I was supposed to learn.
