Generally speaking, the MPA on-the-job postgraduate examination of Wuhan University is not particularly difficult compared with other examinations with equivalent academic qualifications. However, this doesn't mean that you can despise it or don't have to prepare well. Before preparing for the exam, I suggest that you carefully understand the exam outline and requirements, and review and practice in a targeted manner. At the same time, taking more mock exams or communicating with classmates will also help improve your ability and confidence in taking exams.
Personal learning ability and background will also affect the difficulty of the exam. If you have good learning ability and experience, or have some practical experience in related fields, you may pass the exam more easily.
I want to remind you that no matter what exam, it takes some effort and time. If you review carefully and prepare for the exam actively, I believe you will get good grades. Good luck!
