You are mainly careless. Let me give you some advice: carelessness is not a seemingly simple small problem, and you will often lose a lot of points because of this "small problem" We should solve it in many ways. First, be calm, don't panic, and don't be impatient when thinking. Second, think carefully about the problem and think about several situations. Third, learn from the experience and lessons of the usual exams, so that "what you have done and missed will not be wrong again." It can be divided into three categories: foundation, improvement and difficulty. 5. Sort out the wrong questions and sort out a set of wrong questions, and summarize the questions in these questions and practice more. 6. Look at the question word for word carefully and read it several times. 7. Take it seriously. Don't think carelessness is a minor problem. Always take it seriously and do it well. 8. Calm down. Don't make mistakes in haste. I'm sure I can do it. Don't be discouraged. When I can't, I will read the questions several times. I will check it again and again, especially the simple questions I am sure of. Let me count it a few times. Don't be too confident. Ps: Do my best to believe that you will succeed! =^-^= +U！ ! !
