Classroom Chaos (メチャクチャクラスルーム lit. Messed Classroom in Japanese) is the eleventh level of Crash Twinsanity, the second in the Academy of Evil and the only level where Cortex goes solo for part of the time. It continues on from Boiler Room Doom. The level is very easy for collecting Gems as they are all pretty much on the main path. Next to Ant Agony and Totem Hokum, it is one of the longest levels in the game.
