First, if the foundation is poor, I suggest you go to various training schools to listen to courses, understand their teaching styles and services, and choose the remedial classes that suit you.
Second, the civil service examination covers a wide range, and other examinations have no so-called knowledge points. If you have time, refer to the exam outline and exercises, practice systematically every day, and master the answering methods of various questions is the most important. And pay attention to the time. There are a lot of questions in the civil service exam, so you should fully arrange the time for answering them. Giving yourself time to answer questions during practice will get good results.
