Because, after all, Shen Wei also got full marks in the Olympic Games. If the problem is not well measured, it is difficult to solve it at once, so students are really suffering, so they are afraid.

It doesn't make much difference to scum, but I can't answer it anyway; For Xueba, the topic is a bit difficult, but it also needs more thinking. The problem that could have been completed 20 minutes in advance is now done by pinching.

Experience:

Wei Dongyi joined the Olympic Mathematical Training Team in the middle school affiliated to Shandong Normal University in advance when he was in the second grade. In 2007, he was directly promoted from junior high school to the middle school affiliated to Shandong Normal University, and senior one was selected into the national training team of Mathematical Olympiad. In July 2008, he participated in the 49th International Mathematical Olympiad held in Madrid, Spain, and won the gold medal with full marks.

In July, 2009, my sophomore participated in the 50th International Mathematical Olympiad held in Germany, got a perfect gold medal, and then walked to Peking University. From September 20 10 to July 20 14, he studied undergraduate course in Peking University, was selected into the "Top Talents Training Program" of Peking University Institute of Mathematical Sciences, and graduated with a bachelor's degree.
