First, pay attention to the lecture in class and review it in time after class. The acceptance of new knowledge and the cultivation of mathematical model ability are mainly carried out in the classroom, so we should pay special attention to the learning efficiency in the classroom and seek correct learning methods. In class, you should keep up with the teacher's ideas, actively explore thinking, predict the next steps, and compare your own problem-solving ideas with what the teacher said. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt. First of all, we should recall the knowledge points the teacher said before doing various exercises, and correctly master the reasoning process of various formulas. If we are not clear, we should try our best to recall them instead of turning to the book immediately. Finish your homework conscientiously and independently, and be diligent in thinking. In a sense, you should not create a learning way of asking questions without understanding. For some problems, because of their unclear thinking, it is difficult to solve them at the moment. Let yourself calm down and analyze the problems carefully and try to solve them by yourself. At every learning stage, we should sort out and summarize, and combine the points, lines and surfaces of knowledge into a knowledge network and bring it into our own knowledge system. Second, do more questions appropriately and develop good problem-solving habits. If you want to learn the mathematical model well, it is inevitable to do more problems, and you should be familiar with the problem-solving ideas of various types of questions. At the beginning, we should start with the basic problems, take the exercises in the textbook as the standard, lay a good foundation repeatedly, and then find some extracurricular exercises to help broaden our thinking, improve our ability to analyze and solve problems, and master the general rules of solving problems. We should develop good problem-solving habits at ordinary times. Let your energy be highly concentrated, make your brain excited, think quickly, get into the best state, and be able to use it freely in the competition. Practice has proved that at the critical moment, your problem-solving habit is no different from your usual practice. If you are careless and careless when solving problems, it is often exposed in the competition, so it is very important to develop good problem-solving habits at ordinary times. Third, adjust the mentality and treat the trial correctly. First of all, we should focus on basic knowledge, basic skills and basic methods, because most competitions are basic topics. For those difficult and comprehensive topics, we should seriously think about them, try our best to sort out the clues and summarize them after finishing the questions. Adjust your mentality, let yourself calm down at any time, think in an orderly way, and overcome impetuous emotions. In particular, we should have confidence in ourselves and always encourage ourselves. No one can beat me except yourself. If you don't beat yourself, no one can beat my pride. It can be seen that to learn mathematical modeling well, we must start from the usual bit by bit, think more and practice more, be diligent in thinking and be good at doing things, and then we can enter the vast world of mathematics.
