It can be said that the postgraduate entrance examination materials are good, not much. How old are you now? Junior or senior? If you are a senior, because there is not much time left for the postgraduate entrance examination, the supporting exercises are relatively basic, which is suitable for the first round of review and helps to understand the knowledge system, but it is not helpful to improve the postgraduate entrance examination results. It is suggested to read his review books directly, and it will be more efficient to read them in combination with books if you don't understand them. Moreover, unlike the best exams, the number three exam is relatively simple in calculation and thinking. If you are a junior, it is still too early to review. I suggest reading it at least after next summer vacation to master the basic knowledge. In addition, other subjects in the postgraduate entrance examination are actually the same. There are not many excellent materials. Good materials need to be read several times. For example, if you have mastered the questioner's intention in the past ten years, it is not a big problem to get into an ideal school. I'm a sophomore now, and I'm also a national unified exam. The above are just suggestions, I hope I can help you.
