The reasons why I didn't do well in this exam are summarized as follows: 1 I didn't develop the habit of being meticulous at ordinary times, and I was careless in answering questions during the exam, which led to many questions being deducted or even not done correctly. 2 inadequate preparation. Chairman Mao said, don't fight unprepared battles. The implication is that it is difficult to win an unprepared battle, but I didn't act according to this wise saying, which led to my failure in this exam. 3 did not solve the contradiction between interest and course study. I have many interests. As a person, a complete person, an understanding person, of course, I should not let my interests be erased for no reason, just like a machine, not only sad, but also ignorant. But if you seriously delay your study because of your interest, it will be bad, not only bad, but sometimes it is really not worth the candle. What if I fail? Serious reflection is the first: first, what is the reason for this failure? We should seriously think about it and dig up the root causes; Second, what are you going to do next? Determine your own goals, don't be unwilling to go on because of failure, and measure yourself correctly. See what you want, where are your strengths and what are your weaknesses; Third, determine the goal. Know what you want, make a plan, step by step. Failure is not terrible, what is terrible is collapse and blind pursuit. Mathematics is one of the compulsory subjects, so we should study it seriously from the first day of junior high school. So, how can we learn math well? This paper introduces several methods for reference: First, pay attention to the lecture in class and review in time after class. The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay 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. In a sense, you should not create a learning way of asking questions if you don't understand. 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 math well, it is inevitable to do more problems, and you should be familiar with the problem-solving ideas of various 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. For some error-prone topics, you can prepare a set of wrong questions, write your own problem-solving ideas and correct problem-solving processes, and compare them to find out your own mistakes so as to correct them in time. We should develop good problem-solving habits at ordinary times. Let your energy be highly concentrated, make your brain excited, think quickly, enter the best state, and use it freely in the exam. 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 big exam, so it is very important to develop good problem-solving habits at ordinary times.
