It doesn't matter much. Junior high school mathematics is the foundation, and senior high school mathematics is improved on the basis, but the two directions are different. If you are in junior high school, you should pay more attention to the calculation ability. There are few places to really think and the method of solving problems is relatively simple. Personally, I think junior high school is like a stage to cultivate interest in mathematics, but it can't be ignored. After all, the foundation still needs to be laid. In high school, many topics were like advanced ones. Sometimes a topic involves three or four or even five or six knowledge points, and the method of big topic is not fixed. Therefore, thinking will be more flexible and demanding.

Differences in learning methods

Junior high school classroom teaching is small and knowledge is simple. The teacher tries to make all the students understand the knowledge points and problem-solving methods by slowing down the teaching speed in class. After class, the teacher assigns homework, and then through a lot of exercises and extracurricular guidance, he repeatedly understands the knowledge until the students master it.

With the opening of many courses (there are nine courses for students to study at the same time), high school students have to attend at least seven classes every day, so that the study time of each subject will be greatly reduced, and the amount of extracurricular problems assigned by teachers will also be reduced compared with junior high school students, so that the time for concentrated mathematics learning is relatively less than that of junior high school students, and the mathematics teacher will have no time to let all students master mathematics knowledge through junior high school teaching mode, which requires students to have higher self-learning ability.
