Baka to Test to Shoukanjuu

Baka to Test to Shoukanjuu is set at Fumizuki Academy, a school that sorts its students by the scores they earn at the end of their freshman year. High scorers are placed into Class A, while Akihisa Yoshii ends up in Class F, the lowest tier in the school. His class is stuck with the worst facilities available, from rotten tatami mats and broken tables to outdated equipment and worn-out furniture. Things hardly improve when Akihisa finds himself in the same class as his friend Yuuji Sakamoto, while the brilliant Mizuki Himeji is also placed in F after falling ill on the day of the test. Refusing to accept their miserable situation, Class F rallies around Yuuji and takes on the higher-ranked classes through Fumizuki's Examinations Summon Battle system. In these unusual battles, students summon fantasy characters whose power levels are equal to their test scores, turning grades into weapons in all-out clashes between classes. As Class F fights for better perks and a chance to climb the school hierarchy, Akihisa and his classmates must prove that even the weakest group can turn chaos, teamwork, and stubborn pride into victory.
