Li Miaomiao, who had just been fantasizing about her wonderful money-making life next semester, was furious: "Why should I?"

"Why am I the only one out of nine? That's way too brutal!"

Zheng Li doesn't understand business, but he understands logic: "My core competitiveness is me; anyone can attract customers."

Li Miaomiao said speechlessly, "Anyone can give a lecture. It's not like there aren't people in the School of Mathematics who get full marks in their major courses. This year, your School of Mathematics even had someone who won a bronze medal in the Qiu Mathematics Competition."

Zheng Li: "I can get first place, and I won a bronze medal in the Qiu competition, so why should I cooperate with you? He has plenty of people who want to cooperate, and they are cheaper."

"Why don't you bet that I can win the gold medal in the hill competition? Even a 10% chance is not too bad."

Li Miaomiao was unwilling to be cut like this, but she had no reason to object: "Fine, it's a pleasure to cooperate."

"One more thing, you need to take the midterm exam for your major courses."

"Why?" Zheng Li asked. He knew why Li Miaomiao had brought this up, and he needed a reason to convince him.

Li Miaomiao: "When we start classes later, you will need someone from the School of Mathematics to vouch for you. You will need to prove your abilities so that when our potential clients ask their classmates from the School of Mathematics, someone will vouch for you."

"If you only get a perfect score on the final exam, people will think that there is an element of luck or even cheating, which is not very convincing."

"Also, let me tell you that in the first semester of freshman year, the professors in the math department usually give everyone a tough test by making the questions particularly difficult."

"If you can get a perfect score and prove your ability, you won't lack people coming to ask you questions in the second semester."
