Children can't be a math guide in the senior high school competition. Because the math competition in senior four schools is difficult, the math competition guide in senior four schools judges the difficulty of the topic according to the star rating, with one star being the simplest and five stars the most difficult. If the child has not been exposed to the Olympiad before, then start learning simply, which will bring pressure to the child and make him doubt his ability. Mathematics guidance in senior four school competitions mainly guides students to solve problems quickly in mathematics competitions, and shows the importance of problem-solving methods to students through case analysis. It took six years for the math guidance of the senior four school competition, and it was finally decided after constant consideration and revision. It is a serious thinking and active exploration of mathematics education and thinking training for gifted children in China, and it is also the crystallization of our experience and achievements in this work for many years.
