I am a junior high school student who participated in the league, but unfortunately I only won the second prize. I can tell you that it seems that "as long as you win the first prize in the national junior high school mathematics league, you can walk to a key high school" is not reliable, because you can only walk if you do well in other subjects. Mathematics is outstanding, and other subjects are in the top ten in the class. ) The book "Pre-competition Training * Pre-competition Training" in junior high school mathematics league is the best book ten days before the exam, because this book belongs to intensive training, and it depends on the usual basic skills if you want to rank. I think the inscription is quite good (many students in our class have vomited), and the new thinking of exploring and applying is not bad. There should not be much difference between the questions in 2009 and 2008. You find the problem of 08, 07 and 06, and study it yourself.
