1. Listen carefully in class. The in-service teacher is definitely better than us, and he will sum up and give us an award. Listen carefully in class, especially when you don't understand. This is often the point. The key is to master its ideas, not to imitate and copy. Another suggestion is not to spend all your time taking notes in class, because it won't work. Imagine, the high school curriculum is so tight, when do you have time to read notes? It is impossible to concentrate on the whole class in class. The weak foundation can be previewed first, and the good foundation is not needed. Don't be so stiff in class, occasionally divergent thinking, jump from this knowledge point to another knowledge point (of course, this needs to be very familiar with the textbook), which is also helpful for the exam. 2. practice. Practice is necessary, but not more, but better. Do the problem in depth. When you finish a problem (especially one that you can't do yourself), you must think about why you can't do it, what knowledge points are used in this problem, the combination of several knowledge points or something. For some comprehensive questions, try to do it. It combines several knowledge points to familiarize you with them. Also, pay attention to the basic problems. You can't lose the basic questions of the college entrance examination. Usually, we should improve the accuracy and never underestimate the types of questions. Do exercises and learn to summarize. It's best to have a wrong problem book at ordinary times, write down the wrong problems (not all of them, you really don't understand, but not the Olympic math problem, if you are a great person, that's another matter), write down the reasons for the mistakes and analyze the problem. Basically, it is enough to do these two things well. The college entrance examination is not a math contest, nor is it very, very difficult. 90 points is the foundation. If the foundation is not good, read more math books and get familiar with knowledge points, such as compulsory 5. Knowledge points are trigonometric functions, series, linear programming and basic inequalities. Just master these. Don't do any difficult topics in senior one, just pay attention to the foundation.
