The students of Class 3-E and the students of Class 3-A fight against each other to slay the test problems before them, with the students of Class 3-E benefiting from Koro-sensei's unique teaching methods. When the results are revealed, Nakamura scores higher than Tomoya in English; Isogai scores higher than Gakushū in social studies; and Manami scores higher than Koyama in science. Koro-sensei shuns Karma for losing to Gakushū due to studying very little and being overconfident. Terasaka, Yoshida, Muramatsu and Kirara Hazama each earn an additional tentacle for scoring top marks in home economics, resulting in a total of seven tentacles overall. Having won the wager for the contest, the students of Class 3-E decide to use their reward, a summer vacation at an island resort in Okinawa, as the venue for their assassination attempt.
