In fact, at this time, their brains have memorized all the problems. While improving this learning state, they have a very comprehensive understanding of many problems. And junior high school mathematics is not particularly difficult, it is simpler than senior high school mathematics. Many of them are basic questions, and students can master all the knowledge without extracurricular tutoring.
At the same time, there is basically no other learning materials except textbooks and some workbooks issued by teachers. If you want to learn, it will be quick. Only in the process of learning, we must pay attention to the way and understand how to improve our understanding of knowledge in our own learning process. And even if the exam is competitive, it is only a good stretch on the basis. Because in junior high school, if you finish all the subjects, you will have more time to face other problems.
However, in order to achieve the learning goal, some people are not particularly smart, so they use a lot of knowledge points in the learning process. At this time, it is necessary to test whether this person is working hard. Only by studying hard can we better enter the learning state of mathematics. And mathematics itself is a subject that needs more practice and study. Only when people enter the state of studying wholeheartedly can they learn better. However, if you don't grasp the learning methods when you study, you won't reach your goal within one year.
