To tell the truth, as an experienced person, the first textbook we used was "New Practical Textbook for Senior High School Mathematics Olympic Games", with black handouts and white answers; Is a relatively basic book, recommended to beginners;

The topic of "Solving Problems in Senior High School Mathematics Competition" is unknown, and there are many versions. I have done a gold edition, and the topic is more difficult. You have to have some perseverance when you finish it. But it's really comprehensive, I didn't finish reading it anyway; Suitable for promotion and general review.

I really haven't used "2000 Questions in High School Mathematics Competition", and many books are similar in content, so there is no need to use sea tactics;

The textbooks we use are out of print, and the ones upstairs are very difficult, but if we can do it once, our ability is still quite high.

Finally, if it is the sprint stage, all kinds of simulation papers are essential, such as "Sprint the National Mathematics League (Second Edition)", and there are many simulation papers, and the questions in the class are not bad.

The last word of advice: the first prize in the 20 13 competition is not guaranteed, if you aim high: Orsay Classic Geometry and Number Theory Combinatorial Algebra Volume (Volume ***4), Olympiad Series (Volume 16) and Towards IMO (0 1 ~ 1658).
