First, the basic skills of the subject must pass.
1. The concept of mathematics should be fully understood. Many students disagree, but the problem often lies in the concept during the exam.
2. Remember the formulas and basic methods of mathematics, remember what the teacher emphasizes, be good at inductive methods and questions, and you won't panic when you see familiar questions during the exam, and you will be handy when you take the exam.
Second, we should pay full attention to the sloppy phenomenon in exams, which is also a kind of ability. We should correctly handle the following relations:
1。 The Relationship between Examining Questions and Solving Problems
Some candidates do not pay enough attention to the examination of questions, are eager to achieve success, and rush to write, so that they do not fully understand the conditions and requirements of questions. As for how to dig hidden conditions from the problem and stimulate the thinking of solving the problem, it is even more impossible to talk about it, so there are naturally many mistakes in solving the problem. Only by patiently and carefully examining the questions and accurately grasping the key words and quantities in the questions (such as "at least", "a > 0", the range of independent variables, etc. ), and get as much information as possible, in order to quickly find the right direction to solve the problem.
2。 The relationship between "doing" and "scoring"
To turn your problem-solving strategy into a fractional point, it is mainly expressed in accurate and complete mathematical language, which is often ignored by some candidates. Therefore, there are a lot of "yes but no" and "yes but incomplete" situations on the test paper, and the candidates' own evaluation scores are far from the actual scores. For example, many people lost more than 1/3 points because of "jumping questions" in solid geometry argument, and "substituting proof with pictures" in algebraic argument scored poorly because it was not good at accurately transforming "graphic language" into "written language". Another example is the image transformation of trigonometric function in 17 last year. Many candidates are "confident" but not clear, and the points deducted are not a few points. Only by paying attention to the language expression of the problem-solving process can we grade the "can do" questions.
3。 The relationship between quickness and accuracy
The word "quasi" is particularly important in the current situation of large amount of questions and tight time. Only "accuracy" can score, and only "accuracy" can save you the time of examination, while "quickness" is the result of usual training, not a problem that can be solved in the examination room. If you are quick, you will only make mistakes in the end. For example, in last year's application problem No.21,it was not difficult to list piecewise analytic functions, but quite a few candidates miscalculated quadratic functions or even linear functions in a hurry. Although the following part of the problem-solving idea is correct and takes time to calculate, there is almost no score, which is inconsistent with the actual level of candidates. Slow down and be more accurate, and you can get a little more points; On the contrary, if you hurry up and make mistakes, you will not get points if you spend time.
