Baka to Test to Shoukanjuu 2

Sequel to the first season of "Baka", with an OVA prelude to the start of the second season. The story centers around a boy named Akihisa Yoshii, also known as the idiot or "Baka" of the titled anime. He attends Fumizuki Academy, a school where the staff rigidly divides the students based on the results of their academic scores. At the start of the school, students are academically sorted by entrance exam test grades. The higher the grades, the higher the class, and the better the benefits. In this case, Class A is filled with the highest-scoring students; therefore, their classroom was filled with many prestigious items (air conditioners, fancy seats, laptops, a free snack bar, etc.), while the state of Class F is the complete opposite of that, representing the "bottom of the barrel" amenities.
