Hehe, it's not bad to participate in the national competition in the second grade. I must be smart at ordinary times. Actually, I've been there before. See through, whose learning ability is the national competition, learning cross-grade knowledge. For example, if you take part in the competition in Grade Two, you will find that it is easy to do problems without learning the mathematics and memorizing the formulas in Senior High School. Just like when you took part in a math contest in primary school, it was very difficult. But now, in retrospect, I have rich knowledge and found it very simple.

Ps: I still have to seize the opportunity. Junior high school has a national certificate in mathematics and physics and a municipal certificate in English, and you can skip one level. After all, I have been there before ~ ~
