I'm Running a Cram School in the Underworld

Jiang Shufan was a mathematics teacher in a training class during his lifetime. After a sudden death, I came to the underworld and was told that I had to pay social security in the underworld for two years before I could apply for reincarnation. The quality of reincarnation depends on the deposit in the underworld. Jiang Shufan was assigned to do an internship in Po Meng's office. I found that all positions here require examinations. The passing rate for Meng Po's regular examination was 5%. Jiang Shufan took a look and saw that it was easy for Po Meng to prepare the soup with the quadratic equation + sequence problem. The pass rate for the exam to become a regular student is 7%. Listen to the ghost who brought her to the underworld and tell her about the pursuit and encounter issues? Solve triangle problems? Avoid ghost traffic jams anytime and anywhere, and pick up people quickly and conveniently. Even to open a store, you need to take an exam. Diminishing marginal cost and maximum marginal benefit? Economic and mathematical models? Jiang Shufan slapped his thigh, I can do this. It's a pity that one person can't wear multiple hats, so let's do our job. Jiang Shufan opened a cram school. Initially, it only provided training for the vast number of prefecture-level civil servants. Later, more and more people came to visit, and the needs became more and more diverse. Gradually, it became a comprehensive school integrating public examination training, ghost car driving test training, business training, and basic education for children and ghosts. Originally I just wanted to make money for reincarnation. Unexpectedly, he became the principal, the richest man in the underworld, and the president of the Underworld Chamber of Commerce. The most outrageous thing is that Emperor Hades approved the Ministry of Education for her, and she also had to serve as the first Minister of Education in the Underworld. #Just want to cast a good fetus# #maketheunderworld look brand new# #Underworld Emperor is not a human being# Note: 1. There won't be a lot of mathematical content, it's mainly about the beginning of the career line. 2. The underworld is not the underworld, but a private underworld. There are many private underworlds. 3. It's really, really not scary, I swear. Intention: Apply what you learn and enjoy endless benefits
