Again, it is doing exercises. Learning mathematics, the foundation is very important, but on the other hand, if you want to get exam results, you still have to accumulate by constantly doing problems. When writing a counseling book, it is best to have a detailed plan. Of course, planning is also skillful, instead of making a general plan for yourself and completing one chapter every day, as some friends do. Because the content and difficulty of each chapter are different, you can't generalize, otherwise it will easily disrupt your review plan for other subjects. After all, the postgraduate entrance examination is not just about taking a math test. Here's my plan: for example, in the first chapter, I'll give you a sense of the difficulty of this chapter, how many pages there are, how many days to finish it, and then decide how many pages to finish every day. Also, make plans to prevent unexpected accidents, and you should be generous. Don't think it takes time. A good plan will make you get twice the result with half the effort in future review.
Also, be sure to prepare the wrong problem book, because it is far from enough for you to do many problems at once. This requires you to copy down the wrong problems, classic problems and important problems you encounter in your daily practice, mark them in different categories, read and study repeatedly, and write down your own experiences. I suggest using a red pen as a marker, because the red pen is not only eye-catching, but also visually stimulating. After the second time, after the third time ... slowly, you will find that, before you know it, there is no knowledge to beat you.
