1. Choose real questions to judge the types of common questions, so as to determine the review direction. For example: official document writing (applied official documents and conventional languages), case analysis (scenario simulation questions belong to case analysis, because exams can be prepared separately), and strategy paper (big composition).

2. Analyze the amount of problem solving, and conduct time training for each question type in a targeted manner to avoid problems such as insufficient allocation of examination time.

3. By doing problems, we can realize the combination of methodology, new ideas and specific materials. Exercise questions are expensive but not expensive. Some problems are worth studying, doing and correcting again and again, which is of great benefit.
