Is the concise series of three-dimensional college mathematics textbooks edited by Wu, editor-in-chief of National People's Congress Press suitable for postgraduate entrance examination?
Wu's textbook is very good, but it's not the key. You don't have to read it when time is tight.
Postgraduate entrance examination can directly start reading Li Yongle Li Zhengyuan's math review book or Chen Wendeng's high score guide, which has systematic review steps. You have to watch it two or three times and practice the exercises. There won't be much problem.
