In junior high school, there are more courses to learn, greater learning pressure and longer study and homework time.
Therefore, junior high school mathematics should be studied in advance, and you can adapt to the learning life of junior high school in advance. At the same time, if you study in advance, you can learn math better and more easily in junior high school, which can appropriately reduce the academic burden and feel relatively relaxed.
Of course, it is best to find a good remedial class to study in advance. If you live up to the current remedial classes and let students have a little knowledge, it will be counterproductive to enter junior high school. I think I have learned what I have learned, but I haven't fully understood it. In class, it's easy to wander off, which leads to my grades falling.
