The discipline combination of physical biogeography can study medicine. However, although some colleges and universities have no rigid requirements for chemistry, chemistry is almost inseparable in colleges and universities, whether it is medicine or other biology-related majors. Therefore, even if nature can meet the requirements of these majors, the lack of chemical potential will definitely affect the follow-up study, so it is not suitable for applying for medicine.

Changing major is a Chinese word, which means that students change their subjects or majors. Students transfer from one subject to another to study. Take high school liberal arts as an example, students who originally studied liberal arts switched to science or students who originally studied science switched to liberal arts.
