The so-called skills and methods are the places that teachers emphasize when giving lectures and commenting on test questions. Every method and skill has corresponding typical examples, and every example must be thoroughly studied and mastered. For example, in analytic geometry, it is very important to determine the equation from the beginning. What kind of equations should be set for any situation should be mastered when solving problems. Different ways, maybe the final result will be the same, but the steps and calculation in the process are very different, and it may also waste time.
As for the theorems and formulas used in solving problems, they are all basic knowledge that should be mastered and have been consolidated in the first round. These formulas are not clear yet, so I will read a book. After class, I still need to spend some time classifying the exercises and papers that I usually finish, and sum up some commonly used, typical and novel methods.
As for operation, it is the key content of mathematics in the college entrance examination. The calculation of liberal arts mathematics is relatively large, so we should pay attention to the rigor in the process of solving problems, and don't make mistakes in the data and lose points in small places. A wrong step in the process will directly affect the final result.
Lay a good foundation and focus on multiple-choice questions first.
As long as you are willing to work hard, it is possible to make a breakthrough in mathematics.
But if you want to learn math well, you must first grasp multiple-choice questions. Many students say that multiple-choice questions are troublesome and the scores are unstable. To put it bluntly, the foundation is not solid. There are strict time limits for exams. On the basis of limited time, making choices can best lay a solid foundation.
Personally, multiple-choice questions can be practiced more; Especially for students with poor foundation, even if they can't finish the big questions in the exam or the exercise papers handed down by the teacher, they should try their best to complete the selection and fill in the blanks. After finishing, find out the knowledge points that you are most likely to "capsize", thoroughly understand the knowledge points that you used to think were easy to make mistakes when doing simple questions, and then summarize the same type of questions and strengthen training.
In short, we should do more math multiple-choice questions and cultivate the feeling of doing problems; Summarize after finishing, strengthen understanding, and be sure to come back and look through the books if you feel unfamiliar. This is a supplementary foundation.
In addition, the big taboo for multiple-choice questions is the final check, and then change the answer when handing in the paper. In the college entrance examination, few people have tasted the sweetness of checking multiple-choice questions. After the previous students finished the exam, they regretted changing the right one into the wrong one in the last few minutes. It is better to spend more time in the process of making multiple-choice questions than to check the multiple-choice questions at last. Of course, the time to do the problem should not be too long. It takes about 40 to 50 minutes to fill in the blanks.
Don't "sweep" the questions when doing them.
Mathematics big questions, the types of exams are actually quite fixed, such as application questions, which are stable scores, so we must pay attention to calculation. Another example is analytic geometry. Usually you can draw a table with ellipse, hyperbola, parabola and other figures on it, and then compare and summarize their formulas, focal lengths and standard axes, and then use letters instead of operations.
Generally, the first three questions of big questions are not difficult, the last two questions will be a little more difficult, but the last question is also difficult to ask. For these really difficult steps, solving problems sometimes depends on instant inspiration. For ordinary students, you must get the points you can get. If it is a difficult problem that you really can't do, you'd rather put it aside first to ensure the accuracy of the first few big questions.
Many students have a big taboo. I am used to "sweeping the questions" when doing the questions. When they see that the problem is familiar to them, they just think about what they can do in their minds. They just go through the motions without putting pen to paper. This is not good. Mathematics depends not only on your method of solving problems, but also on whether you can get the correct results in the end. So, don't just look at the list and think about not doing the problem, but try to combine your brain with your hand.
In terms of the amount of questions, it is enough to insist on doing a set of questions for 2 ~ 3 days, and generally do exercises handed down by teachers. When you do it, you should finish it within 2 hours according to the test requirements. Ten days before the exam, do 2 ~ 3 sets of hands to keep fit. Then look through the notes made in class at ordinary times, summary of test questions, textbook formulas, etc.
