April Fooling

Today I pranked my classes like they've never been pranked before. I told them they were having a pop quiz that would help to decide whether or not they would advance to the next level. I then gave them the below quiz.

Many of them protested that they had never seen the words before; I told them they probably didn't work hard enough on their online homework. After the inevitable failing grades, I told them they probably wouldn't advance with scores like that.

Then, I explained the concept of April 1, and they wanted to kill me. But they had to admit it was a good prank.
