When a teacher yells at you to study certain stuff for a test, you spend all night memorizing it, only to find out the test was about something else entirely.
My teacher screamed at me to study fractions. The test was about how to throw a punch.
I studied the periodic table for the science exam. It was about how to beat up your crush.
The teacher told us to learn all the states. The test asked what color my socks are.
