One day I walked into my favorite class for a test. Now, I am a stellar test taker. Not intending to brag on myself, but I am. I study, sure, but I also don't get nervous and have an easy time navigating my way through them. They don't bother me. I am usually very quick, one of the first people to turn my answers in. But not this day. This day, I was the last person in the room, and time was running out, and my brain was stalling. I could not find a way to reason through a problem that I knew I should know.
