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. In addition, in fact, accounting does not have high requirements for mathematics, and the mathematics subjects studied are the same as the above marketing subjects. The key point is that most of the mathematics used in some accounting courses in senior grades are high school level, which is very simple. You don't have to worry about learning marketing and accounting because of the basic problems of mathematics, but the requirements of economics and finance are relatively high, especially in some key universities, where the mathematics level of economics and finance majors is relatively high.
