As far as I know, the requirements of marketing for mathematics are not high, which are limited to calculus, linear algebra and probability theory that all students majoring in economics and management have to learn. In college exams, it is very easy to pass, and teachers will give questions or key points, so there is no need to be afraid to say that the math foundation is not good, and coping with the exam has nothing to do with it. There is basically no need to learn mathematics in subsequent courses, that is, freshmen and sophomores will learn mathematics in the last semester.
