The characters of the Baka and Test series were created by Kenji Inoue, with illustration and character design by Yui Haga. The story centers on a boy named Akihisa Yoshii, also known as the idiot or "Baka" of the title. He attends Fumizuki Academy, a school where the staff rigidly divides its students based on the results of their academic scores.
The worst class with the worst facilities, including decrepit tables (later changed into upturned cardboard boxes then to large clipboards with rope to hold them up), tatami mats and under-stuffed sitting cushions; 47 males, 2 females, and Hideyoshi make up the class. There is a total of 149 boys enrolled in the second-year class, so approximately one-third are in Class 2-F.
The best class with the best equipment; 24 males and 26 females. The top 10 of Class 2-A are said to be so strong that they are in a league of their own compared to other Class 2-A students.
The second worst class in terms of grades next to Class 2-F. However, unlike Class 2-F, which is populated primarily by idiots, Class 2-E's students are mostly athletes, meaning that they can last longer in a summoning battle than most other students.
