The enrollment ratio of public health postgraduate entrance examination in Wuhan University is 50 1. Because we know that Wuhan University is a key major, the competition is fierce, the admission rate is low, and the number of people taking the postgraduate entrance examination for public health is relatively large, but the country needs a certain number of talents, so the proportion of their postgraduate entrance examination is 50 1, which means that 50 people can take the exam only by hiring one, which is quite low, so it is still difficult to get into Wuhan University.
