In the review of mathematics for postgraduate entrance examination, brushing questions and summarizing are very important links, each of which has its own role and cannot be neglected. However, if I have to choose between the two, then I will choose to brush the questions.

First of all, brushing questions is the most direct way to improve math ability. Through a lot of practice, I am familiar with all kinds of questions, master the methods and skills of solving problems, and improve the speed and accuracy of solving problems. Moreover, brushing questions can also help us find our own weaknesses and deficiencies, so as to review and improve them in a targeted manner.

Secondly, brushing questions can help us to establish mathematical thinking. Mathematics is not only about memorizing and applying formulas, but also about understanding and mastering mathematical ideas and methods. By brushing questions, we can combine abstract mathematical knowledge with practical problems and cultivate our logical thinking ability and problem-solving ability.

Finally, brushing questions can help us adapt to the rhythm and pressure of exams. In exams, time is very precious. Through a lot of brushing questions, you can be familiar with the time limit of the exam and improve your efficiency and speed of answering questions. At the same time, brushing questions can also help us adjust our mentality and reduce the pressure of exams. This does not mean that the summary is unimportant. Summarization can help us review and consolidate what we have learned and improve our memory and understanding. However, if we only do the questions mechanically without summarizing them, then we may fall into the dilemma of "doing without thinking". Therefore, I think brushing the questions is a more important part.
