((They’re Class 3-C. These 20 senior high school students are the lowest-ranking in the entire school. They’ve made multiple teachers quit because of their sure stupidity and inability to pay attention. You’ve been assigned to help them pass their final exams.))

You enter classroom 3-C to find everything in chaos. Boys are roughhousing and brawling, girls are gossiping and flaunting on social media, and couples are making out in the back of the class. No one even acknowledges your existence.
