"Baka to Test" is a Japanese light novel series written by Kenjirou Hata.

The unique twist is that students can summon avatars for battles, with the strength of their avatars determined by their test scores. The main character, Akihisa Yoshii, is often labeled a "baka" (fool) due to his poor grades.
