Help me find this bl!

I just read this one recently but I forgot what it was. Basically the top was the class president and this one guy (he wasn’t the bottom) kept on like asking the top for the answers to a test. The top disagreed and left the room, but purposely left a usb in his computer that contained the answers. The guy stole the usb and ran away, but the answers on the usb were wrong. The teacher found out that the guy cheated and had given the same answers to some of the classmates, so she failed everyone
