The test center with high number B in 602 is closest to Math II, so we don't test probability, but there are more series and triple integrals than Math II, and the difficulty is closer to Math III, that is, the topic is relatively simple. Therefore, I suggest that you review the economic mathematics version with Erli, that is, the version of Mathematics III, but don't look at the probability and statistics section. Triple integral. Just look at the textbook. It is said that the latest edition of advanced mathematics textbook of East China Normal University will have original questions.
