She's So Awesome

"I don't think so. The teacher looks very surprised. It's possible that Leng Xiaoyao's answer is correct."

"Right, but I still can't believe that Leng Xiaoyao knows the answers."

"…"

"Jesus, Leng Xiaoyao's answers are correct."

"She could really answer the questions."

The students who knew the answers were extremely surprised.

Afterwards, Leng Xiaoyao wrote down the answer to the third question.

Because no one in the class knew the answer, they didn't know whether Leng Xiaoyao's answer was correct, but she had written down the correct answers to the first and second questions, so they thought she might really know the answers.

The students who didn't know the answers to the first and second questions couldn't tell whether Leng Xiaoyao's answers were correct.

The math teacher, on the other hand, was completely shocked because he knew that Leng Xiaoyao's answers were all correct.

How did she suddenly become so smart?
