Brush the questions closely to the exam outline. Textbooks and outlines are always the foundation of the preparation fund. Even if it is important to brush the questions in the fund examination, it cannot be divorced from the outline, because the proposer must write the questions according to the requirements of the outline and teaching materials.

When you encounter questions that you can't do or do wrong, you should review the knowledge points involved, sort out the relevant content, and summarize the ideas and rules of answering questions. Each question should correspond to the knowledge points in the book.
