When doing a problem, if it is difficult to determine the correct answer at the moment, you can use the knowledge you have learned to rule out the options of the problem one by one. ③ Analytical comparison method. We can also analyze and compare all the options and finally decide which one to choose through thinking.

2. judge the problem. We must first find out all the knowledge points in the problem, and then judge each knowledge point. As long as there is a mistake, the question should be marked with "X"; Be careful when you do the questions; 3, material analysis questions, first of all, we must be bold, do not have fear of difficulties.

Politics: For the political open-book exam, sort out, classify and label it. The whole class subscribes to a set of middle school students' political newspapers, from which some useful concluding remarks can be obtained, taken to the textbook and brought to the examination room for easy search. History is to sort out some major historical stages (or historical events) first, and then think about what test sites there are in these historical stages. Of course, the knowledge points are in the textbook, so you have to be very familiar with the textbook. Junior high school history mainly focuses on events and their effects, and there is no need to explore the reasons. Therefore, as long as you are familiar with knowledge points, history is given points; If your politics is a closed-book exam, it will be less difficult and effective for comprehensive recitation of textbooks. In a word, we should attach importance to textbooks, and it is best to make mock papers for previous joint exams. Believe it or not, as long as you do more simulation papers, you may get full marks in all subjects except Chinese.
