The primary examination pays attention to the understanding of basic knowledge, and the difficulty of the examination is not so high, but the questions are wide and flexible. Generally speaking, the preparation time is not less than two months, but everyone's foundation is different and the preparation time is different, so the preparation time will be different.

You can follow this step: after registering for the exam, study the whole textbook and have a preliminary understanding of the whole exam content. It is recommended that zero-based candidates follow the advanced and basic textbooks. Before mid-March, review the second round as a whole, focusing on reviewing the teacher's courseware or handouts and strengthening the practice of related topics. Starting from April, we should return to the examination materials, review the wrong questions and deepen our impression. During the sprint in May, don't engage in sea tactics, do the previous topics thoroughly, and watch more lectures summarized by the teacher.
