Generally, middle schools will have training for this kind of competition. If you want to get good grades in the competition, you should study hard. Many high school competitions are about the knowledge of advanced mathematics in universities. I don't know what grade you are in, so you can usually ask the teacher. There must be such a competition in previous years, and the information teacher must have it. You can ask the teacher. The competition topics involve relatively simple knowledge in advanced mathematics. When studying, you can look at the competition materials in your spare time and then learn some simple advanced mathematics knowledge. Then some questions will be clearer and simpler. After all, those competition problems are difficult to solve with high school knowledge, and most of them are what you have learned.

I wonder how your math scores are? There used to be a girl in our class, and every exam was around 130 and 140. I forgot whether she won the second prize or the third prize in the math contest. Do you still make up classes in high school now?

It is reasonable to set aside one or two mornings a week for long-term practice. Learning is the most important thing. After all, mathematics is not the only subject. Some questions in the competition are repetitive, and the tactics of asking questions about the sea still have some effects. Of course, it is also very useful to study advanced mathematics in your spare time. Most of the knowledge in the first volume of Advanced Mathematics is duplicated in senior high school, so it is not difficult to learn. You will be relaxed when you go to college. Science and engineering have to learn mathematics, but liberal arts and science have been abridged.

Information and so on, go to the bookstore to see if there is any. I used to buy them in the same class. In a word, don't forget to ask your math teacher. His experience is still very good. I wish you good grades!
