This game is very difficult. It is better to give up without some basic skills in the competition, but self-study is still possible. As for what books to read, it depends on your own situation. It is more difficult for beginners to read Olympic classics. It's best to read some books specifically for the league.
I reviewed my knowledge and went straight up.
As for the allocation of time, don't just spend an hour and a half on a topic, think as much as you can, and don't make mistakes in key calculation points. As long as you have some ideas, the topic is still very simple. Review can still look at the topics of previous years. After taking the test center, there will be more circles and functions, so you don't have to teach yourself.
There is nothing to say about experience. Be careful and don't make mistakes on key points. The difficulty of big questions is gradual. The first question is generally not difficult, and every question will be related. There's really nothing to do but guess. ....
I always feel that the usual accumulation is more critical, and I still have a lot of knowledge about Olympic mathematics. Finally, I wish the landlord good results!
Give points for writing so much. )
