It's different. In junior high school, most students choose to improve synchronously in the outline of the senior high school entrance examination, and only a few students choose to study Olympiad and take the road of competition. But high school is completely different. Mathematics in high school is very difficult, which requires you to have a solid foundation in junior high school. Sometimes you just give up if you really don't understand, so I still suggest that you don't take the road of competition in high school unless those students who are particularly good at Olympic Mathematics in junior high school are different from them. For you, going to a good university is not a problem as long as you have a solid foundation, thoroughly study the contents in the college entrance examination outline and have time to do some promotion questions.
