In 10th grade I ha a business class that I never wanted to take. I slept through most, if not all, of the class every day. When teacher passed out the final test, I took mine (after initially declining it) to use as a “pillow”. As I was putting my head down, I noticed a question, and realized I knew the answer. I wrote it down. Then another, and another, and……….
I had the highest score in the class. Not a good grade mind you, but the best. (Doesn’t say much for the teacher’s teaching skills, does it?)
