1, after the first stage of math review in senior three, enter the comprehensive review stage. You can neither repeat the basic review, nor be too comprehensive and divorced from the foundation. Comprehensive review must be closely combined with the college entrance examination to improve the review efficiency as much as possible. 2. The college entrance examination adopts multiple-choice questions and fill-in-the-blank questions. In addition to highlighting basic knowledge and skills, we also examine students' abilities. The ability to use multiple-choice questions and fill-in-the-blank questions focuses on the speed of solving problems. Therefore, when reviewing multiple-choice questions and fill-in-the-blank questions, we should pay more attention to the training of problem-solving methods of multiple-choice questions and fill-in-the-blank questions on the basis of basic knowledge, strengthen the training of special methods on the premise of mastering conventional methods, and improve the answering speed on the premise of doing the questions correctly. As clearly pointed out in the "Examination Instructions", we should "think more and calculate less". 3. Strengthen the training of multiple-choice questions and fill-in-the-blank questions. There are the following methods: with the help of the knowledge of related concepts, properties, theorems, laws and formulas, through strict reasoning and accurate operation, the correct conclusion is drawn, and then the corresponding choice is made according to the options given in the stem. Direct method is often used for problems involving concept and property analysis or simple operation. Replace the general conditions of the topic with special values (special numbers, special positions), draw special conclusions, test each option and make correct judgments. Commonly used special cases include special numerical values, special series, special functions, special graphs, special angles, special positions and so on.
