Gakuen Kishi no Level up!

Reincarnated with memories of his previous life, Soma gains the rare ability “trial and error,” which lets him check skill levels numerically and improve many of them evenly. He dreams of attending a knight-training school, where students are assessed and assigned to classes according to their abilities. At the entrance ceremony, students with a combined skill level above 200 are expected to enter the elite Blue Dragon class. Soma’s total is 1,012, but the assessment machine cannot measure four-digit levels, so it misjudges him and sends him to the problem-student class. Using his ability, Soma begins a major upheaval at the aristocratic school.
