It depends on the school and major. If you only test microorganisms, such as those in the School of Life Sciences of Wuhan University or the Institute of Microbiology of Chinese Academy of Sciences, you tend to study basic theories, mainly the physical and chemical properties of viruses and ordinary microorganisms. If you take the Wu Da exam, you don't need to take the exam in mathematics, politics, English, microbiology, molecular biology (or biochemistry, depending on the specific application direction, find it yourself).

Schools that want to take part in science and engineering, such as South China University of Technology, basically have to take math exams.

But if you are good at math, it is also very useful to learn microbiology. Now is an interdisciplinary era, and mathematics is the basic subject.
