Can Olympic Mathematics be taught by itself? Tell me about your experience and methods.

I think so, although I was taught in a competition class.

It is important to choose a good book. Especially in the initial stage, it is impossible to distinguish between good and bad problems. If the book is poor, it will lead people astray.

Mathematics is a kind of thinking the game, so enjoy it.

You can also read some good questions in the post bar.

You can read a good competition book, or you can read a math popular science book written by a mathematician.

But don't just look. It is best to think deeply about any problem first, come up with the best solution, see if the solution in the book is more ingenious, and you can better understand its beauty if you can't think of the answer.

If you are preparing for the league, you should pay attention to small problems and train in a limited time.
