The question types of the National Senior High School Mathematics League have just changed: there are only fill-in-the-blank questions and solution questions in an exam, with a score of * * *100; There are four big questions in the second exam, each with 50 points; A score of ***300, who participated in a provincial preliminaries before (slightly more difficult than the college entrance examination, and all those who have been trained can pass), as for the national league, it is estimated that if the score is above 170~ 180, he will definitely win the first prize at the provincial level, and the college entrance examination is generally 10, so he may be recommended to walk and enroll students independently. The top players in the league (not necessarily the same number in each province) form provincial teams. If you enter the provincial team, you will basically go to Tsinghua Peking University; If you get 200 points, you can basically go anywhere you want ... you have basically finished all the books in high school, otherwise you can't answer the test; It is difficult for you to answer the second test without training. It's different from junior high school. In high school, there is a group of people who don't attend classes every day. When the league is fast, they hardly attend classes. The first test and the second test will be completed in one day. If you are interested, you can learn several competitions. If it's just for extra points or contributions, then learn one. Nobody has that much energy. It's not too late for you to start learning the competition, but you should be prepared to work hard, or you will get nothing at all. It is best for schools to have special teacher training. Self-study is not easy.
