Ep 21. XX Time

Koro-sensei comes up with an unorthodox way to train the students for their final exams: a machine that slows time down for anyone inside its field of effect. The class's objective is to obtain test-taking pointers from the AI, called "Testuevos." But when the machine goes berserk, Koro-sensei and the students must face the ultimate test of survival in a world where time moves at a snail's pace. In the meantime, time is running out for the students to get a passing grade on their final exams, with pressure building up for them all. Despite the extreme challenge posed to them, the students must overcome their fear of failure and tread along the path of success. Will they be able to do so, or will they fall prey to the machine's malfunction that slows time to a halt?
