In the Port Mafia, But Focused on the College Entrance Exam

Chizuru transmigrated with the complete set of Five Years of College Entrance Exams, Three Years of Practice Tests, and a "Study God Training" System appeared in her mind. To survive, she had no choice but to apply for an ordinary job as a wage laborer. But whenever she pulled out her practice book and got ready to work through a set of questions, either the shopping mall exploded or someone jumped off a building somewhere. There was never any peace and quiet. In a fit of anger, Chizuru dragged everyone into a massive college entrance exam. System: "Exam over. Player Chizuru ranked first in physics. Exam topic triggered: atomic nuclei. Superpower [Big Bang] activated." Big Bang: It is the origin of everything and the end of all things. Activate the superpower [Big Bang] to reverse time and return to 24 hours earlier. After arriving on the day before the incident, Chizuru sent an anonymous tip straight to the Metropolitan Police Department. The bomb fanatic/stalker/rapist/serial killer/serial mutilator caught red-handed: ??? And so the people of Yokohama began a life of misery. Every day they had to take either a classical Chinese exam or a math exam. Once they had barely survived those two, thinking they'd escaped the abyss, they found civics, history, geography, English, Chinese, biology, physics, chemistry, PE, art, and music waiting for them. Chizuru: Another day of studying hard! \(￣︶￣)/ It's probably an uplifting story about how I want to study hard, but nobody will let me, so I can only send them all to prison. Theme: Study hard and make progress every day.
