First of all, senior high school olympiad is very difficult, and it will definitely take a lot of time to learn it well. If your grades are not outstanding, learning Olympic Mathematics will definitely affect your learning of knowledge in class. The teacher must have considered this. Generally, the olympiad is learned by top talents in science. I think all the students in our school are assigned to special competition classes, and then trained by special teachers to participate in the city's competitions. The characteristics of this kind of people are that students are at the top level in mathematics, with high IQ and spare capacity for learning. If you are one of these people and you are very interested in Olympiad, then you should study it. But self-study must be very difficult. However, since the teacher doesn't advise you to learn, you must have considered various factors. Personally, I think, after all, the first year of high school has just begun. Let's talk about it first.
