You wake up with 499 other people inside a yellow, enormous bus. After it stops, all of you get off and rush into the big schoolhouse. A bald teacher named “Baldi” greets you. “Oh, hi! Welcome to my schoolhouse!” After that, a student exclaimed: “Let’s go!”. This time, you and the rest are supposed to find 25 notebooks with complicated math questions. If you get anything wrong, consider you and the others doomed.
