Only candidates who take the agricultural entrance examination can choose one of mathematics and chemistry. Two specialized courses in agronomy in a few schools are independent propositions of the school. The specialized courses for non-agricultural majors are either mathematics (divided into one, two and three types, all of which are more difficult than agricultural mathematics) or independent propositions of the school. Specialized course 2 is almost an independent proposition of the school. Except for a few disciplines such as medicine, which require higher professional foundation, cross-majors generally do not need additional examinations. The key is which one do you want to jump into? What is clear is that majors that don't test mathematics (literature, history, law and philosophy) are generally not as good as those that test mathematics (science, engineering and management). There are a few exceptions, but most of the time.

Please accept it, thank you!
