The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay special attention to the learning efficiency in the classroom. In class, we should closely follow the teacher's ideas, actively think, predict the next steps, and compare our own problem-solving ideas with what the teacher said. Review in time after class, leave no doubt, ask the teacher or classmates in time if you don't understand, and don't skip over what you don't understand. After class, we should also pay attention to the study of basic knowledge and the cultivation of basic skills, and remember more formulas and theorems, because they are the key and necessary conditions for learning mathematics well.

Second, do more exercises and develop good problem-solving habits.

If you want to learn math well, it is inevitable to do more problems. Of course, doing more questions does not mean doing sea tactics. The questions you do should be representative. You can't just grab your beard and eyebrows and do whatever you meet. Some problems are suitable for us to do, while others are beyond our ability. Doing these problems will only waste our precious time and will not achieve any results. The difficulty of the questions to be done should be moderate, and by doing some representative questions, we strive to draw inferences from one another. Mathematics is a very logical subject, which requires careful thinking, orderly problem solving, skillful use of correct problem solving methods in the process of doing problems, and mastery of the law of solving some basic problems. Only with a lot of training, watching more and doing more, practice makes perfect, can you cope with the exam without being confused.
