This statement is wrong, it is the third year of mathematics for postgraduate entrance examination. The contents of the third examination of mathematics for postgraduate entrance examination are: advanced mathematics ***84, linear algebra ***33, probability theory and mathematical statistics ***33. The difference between Math 1 and Math1is mainly in the high number, which is much less, such as the part of vector algebra, and where the double integral has multiple integrals, several important formulas are missing, such as the difference between line integral and area integral. Look at your textbook, and the chapters above should be marked (especially where you only study mathematics). As for line generation and probability, there is not much difference. Sometimes the single question of probability may be a little more difficult than that of mathematics, but there is not much difference. You should read the textbook first, then use Li Yongle's complete mathematics III+660 questions, and finally do the real problem analysis in recent years. Try to read the whole book and 660 questions two or three times (depending on the time), and don't trust the tactics of betting on questions and asking questions. Reading the whole book and 660 questions three times is definitely better than reading six different books.
