First, read through the textbook and don't do the questions in a hurry. First, study how to get concepts, theorems and properties, and how to infer them.
Second, do a good job in after-class exercises of textbooks, and don't ignore them because the topics are simple. In fact, the most difficult topics are all evolved from simple topics. When doing simple topics, we should pay special attention to summing up ideas. In fact, the questions in the textbook are still very valuable, and many classic ideas for doing the questions are summarized from the textbook exercises.
Third, do exercises according to the teacher's requirements, focusing on accuracy rather than quantity. Generally speaking, teachers are very experienced in teaching. It is completely correct to follow the teacher's rhythm. What you should pay attention to when doing the problem is to establish a wrong problem book and a summary book of ideas, write down some novel and error-prone questions, and keep reading, so that you will be familiar with them in the future.
Fourth, generally speaking, the number of math test questions in senior one is not too much, and it is not too difficult. If you feel a little short, you need to speed up. I suggest that you just struggle with the problem when you usually do it. You can take time to do it, and the speed is also exercised. It's hard to do simple things. Of course, the math test questions in the college entrance examination are still somewhat difficult. How to turn these problems into simple problems lies in the first three steps I mentioned, thus laying a good foundation. Of course, speed must be practiced.
Fifth, emphasize the problem of solving problems in detail. Don't stop listening to the teacher explain other problem-solving methods just because there is a problem. You must absorb it completely. First, pay attention to whether there is a simple method. Second, once the question type changes, your method may not be applicable and you need other methods to do it.
Finally, if you are a senior three, find some good review materials for the college entrance examination and read them from the beginning when you are finished. Don't be insatiable, just do it without remembering. This is a very serious mistake.
