The Private Detective 4

Although he saw that the test paper was filled with answers, he did not think that all the answers were correct. It had only been half an hour since the start of the exam. It was impossible for this student to finish the test paper. These Mathematical Olympiad questions were set by the entire school's mathematics teachers after discussion. It was almost comparable to the real Mathematical Olympiad Competition. It was impossible to work out all the questions in half an hour unless she didn't need to think at all. Even so, she was pressed for time to write all the answers.

The teacher did not say anything else after hearing her resolute reply. He could only accept her test paper.

The other students were shocked to see Ye Leng'an hand in her paper. Or maybe they already felt shocked to see Ye Leng'an in the examination room.
