Well, I just don't know if you want to go to another school or Fudan. This still needs specific analysis. If your undergraduate course is a poor school, and you want to enter Fudan University, then let's sign up for a class honestly. Needless to say, it costs a lot of money to apply for classes. Now many people choose to take online courses. Teachers in online classes are generally good, hundreds of thousands. I signed up for the Tiandao Postgraduate Entrance Examination. There are also tens of thousands of dollars, which I can't bear. If you want to get into a better school from Fudan University, such as Tsinghua Peking University, what you need most is specialized courses. After all, you are from Fudan, and the foundation of public courses is definitely not bad. The most important thing to apply for a class is to tailor it according to your own situation.
