The difficulty in math class is mainly due to the students' own achievements. If your grades can be ranked in the top three, there should be no problem. When I was placed in classes in the first grade exam, I took three courses other than language number, but they were all very difficult, and there were Olympic math questions in them. The math class (that is, the experimental class) mainly focuses on math scores, and we can't go to class until we reach 80 points in that class.
Anyway, come on ~ even if you don't enter the math class, the parallel class is not bad ~
