I am a major in international trade and practice, and I don't have high requirements for mathematics. Some schools basically don't have high numbers in both majors! However, the requirements for English, especially oral English, are very high, and the requirements for professional knowledge are general, but it will be easier to learn the basic professional knowledge well. The most important thing is English. If it is international finance, it needs some calculations, which has little to do with mathematics, but you should be familiar with the bank's exchange rate and know how to convert it, such as hedging. The main fields of finance are monetary banking, commercial banking management and central banking. In short, if a university studies international trade, it should take more certificates, such as cashier, foreign trade salesman, export salesman, freight forwarder, warehousing, accounting, and CET-4 and CET-6 certificates. There are not many classes in general universities, depending on how you arrange them reasonably. During college, you should have a plan. Many people graduated from college with only a diploma and learned nothing else. I feel that they have learned for nothing in recent years, but some students have gained a lot. Also, college communication is very important. You should take part in more student activities, and don't be an otaku!
