The information science of Wuhan University is mainly information management, and it is a liberal arts major. I know nothing about math and computers. Specific subjects can be found on the enrollment website of Wuhan University Graduate School.
As a famous university in China, Wuhan University is also the big brother in the field of library and information science, and it is difficult to get a master's degree in information science. If you have no confidence in your grades, you'd better not take the Wu Da exam. Why don't you change to a second-rate university?
