If the requirements are relatively high, I hope not only to know the general content, but also to use something. Then you can find some textbooks for vocational colleges or liberal arts.

If it is a postgraduate entrance examination, Tongji's high number is necessary, and it needs real questions over the years, as well as some self-favorite counseling books.
If you are a graduate student in the Department of Mathematics, I recommend Pei's Typical Problems and Methods in Mathematical Analysis and his Lecture Notes on Mathematical Analysis Exercises. Xie's book is extremely difficult. If you do it, you'd better discuss it with your classmates, otherwise it may never be done. . . .
