Although mathematics is difficult, it is not impossible to learn it well. As long as we persist in studying, think independently and master mathematical thinking and methods, it is not as difficult as everyone thinks.

First of all, it is necessary to listen carefully in math class and preview before class, so that we can better keep up with the teacher's lecture ideas, but it is not enough to understand the light energy in class. You can't learn math at all, and this is just the beginning.

Secondly, after listening to mathematics, we should do problems, improve our training, master new knowledge and learn new courses. Mathematics in senior high school is more difficult. The tough battle begins bit by bit, and the difficulties need to be overcome slowly. Finally, summarize the wrong questions. Even if you correct them and keep improving, mistakes are inevitable. Correcting can make progress, and it is also a step to learn math well and improve your grades.

There are so many elective courses and compulsory courses to learn in high school mathematics, and there is a lot of knowledge and time, so there is no chance to catch my breath. The knowledge of mathematics comes from one link to another, so try not to fall behind, and it is difficult to catch up halfway.
