Metropolis: I Was Exposed in the Mathematical Olympiad Surprise Test Because I Controlled My Scores

In a surprise math test, Xia Fan, as usual, controlled his score at 90% to pass. The academic committee member who usually gets full marks in mathematics cried: "This exam is really bad. I'm sorry, teacher!" The female top student in the top five in the class cried loudly: "I completely failed the test this time. The test paper was too difficult. I only answered half of the questions and couldn't even score 40." The female monitor, who was number one in the class, cried loudly: "The test questions this time are too difficult. Even my fifty points will be a problem, woo woo woo." Xia Fan: "This is just the daily Versailles of your academic masters. Even I can score 90 points!" All the top students said: "But didn't you realize that this time the test papers are all Mathematical Olympiad questions?" Xia Fan: "It's over. I finished it in less than ten minutes. I didn't pay attention at all. This dress is too big!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
