Baka and Test: Summon the Beasts

Students are placed into different classes at their elite school based on their performance in the Promotion Test. The top-ranked A class enjoys the finest facilities, while the struggling F class makes do with broken furniture and worn-out tatami mats. To move up in rank, students compete in the Examination Summons Battle (ESB) system, where they summon characters based on their test scores and use them to challenge other classes.
