The difference is not big, the grammar and words are similar, and the postgraduate entrance examination for French will not involve any texts, mainly the grammatical tense of words, which is almost the same. In fact, it generally makes no difference what you look at, but to be honest, if you study Ma Xiaohong in the postgraduate entrance examination, it is still very reliable. After all, it is a textbook for French majors, especially the words and grammar are well organized and comprehensive, so you'd better read it when you have time.
