Gakuen Kishi no Level Up! Level 1000-goe no Tenseisha, Ochikobore Class ni Nyuugaku. Soshite,

Soma, who reincarnated with the memory of the previous life, was awakened to the rare ability "trial and error" that can confirm the skill level numerically, and thanks to that, he was able to raise various levels evenly. At the entrance ceremony at the knight training school that he admired, the students' skill levels are judged and classified, and the top class "Blue Dragon" is certain if it exceeds a total skill level of 200. However, Soma's total level at this time was 1012, which should have been far above the margin , but the judgment machine couldn't measure the 4-digit level! As a result, even though he had the highest academic ability, Soma is put into the problem child class. But with the skill of "trial and error," Soma causes a big revolution in the aristocratic school! The school fantasy presented by the strongest reincarnated person in the dropout class begins!
