In The Family Game, the plot centers on Shigeyuki’s new tutor, Yoshimoto Katsu. Katsu’s tutoring consists mostly of sitting Shigeyuki in front of test-prep materials, and punching him if he doesn’t study. Shigeyuki’s dad promises Katsu a huge bonus if Shigeyuki hits his target score, so Katsu has incentive to keep smacking Shigeyuki until he improves. In the end, Shigeyuki does get the desired test result.
