To learn finance, you must learn mathematics, and mathematics is also very important, especially for the postgraduate entrance examination. What textbooks to learn depends on the school. Some schools learn different textbooks, but the content is similar. Advanced mathematics and calculus (calculus is included in advanced mathematics, but some schools don't study advanced numbers, and calculus is studied separately), probability theory and mathematical statistics, linear algebra and econometric statistics are all mathematical knowledge. Because I study finance, I hope it will help you ~ ~
