The top 50 in the math contest are all boys, but no girls. There is only one girl in the top 50 physics department.

After high school, are boys' grades significantly better than girls'?

The second is the grade distribution of members, and the students in Grade One and Grade Two are high.

80% of the students in the top 50 of mathematics in senior one and senior two. What does this mean?

Senior one students can join the national training team before they finish learning the textbooks. Do all the contestants study in advance? Have you finished learning high school knowledge in junior high school?

Third, the members are basically from prestigious schools.

There are many famous schools such as the High School Attached to the National People's Congress, Chengdu No.7 Middle School, Shanghai Middle School, Bashu Middle School, East China Normal University High School and Hangzhou No.2 Middle School. What does this mean? Are the competition teachers in these famous schools very strong? It is rumored that many middle schools in China have set up "Qiu Chengtong Youth Class" to recruit students for primary schools. Is it true to encourage excellent middle school students to get in touch with university knowledge such as calculus and linear algebra to prepare for the competition? Will studying in advance be a trend?

Fourth, there is a big gap between strong and weak provinces in the competition.

There are 260 people in 2/kloc-0 provinces in China, among which Zhejiang Province, as a strong competition province, is far ahead of other provinces with 44 people selected.
