The trick of passing subject four is to browse the information quickly, narrow the scope of the question bank, screen the questions again and summarize the rules. The following are specific instructions: browse the material quickly: first, browse all the questions and answers in the material quickly. You only need to look at the answers for multiple-choice questions, and you don't need to look at other options, because the first impression is very important. Remember the answer, and you will have a preliminary impression when you do the problem in the future. Narrow the scope of the question bank: There are many simple questions in the question bank. After practice, delete these simple questions and you don't have to read them any more. In this way, the remaining problems are only about half (different from person to person). Screen the questions again: practice the remaining questions from beginning to end in order. After completing each part of the questions, highlight the wrong questions and uncertain questions in red font, and strengthen the memory of these questions respectively, especially the key assault before the exam. Summarize the law: for some questions that can only be recited (such as how many meters, how many yuan, how many kilometers, etc. ), summarize the rules and try to remember easily.
