The multiple-choice questions in the new college entrance examination mathematics paper are changed from the original "12 multiple-choice questions" to "8 multiple-choice questions and 4 multiple-choice questions", and the multiple-choice questions are composed of 1 stem and 4 options. There are at least 2 correct options among the options, and the correct answer will be 2, 3 or 4. If there are wrong options in the answers selected by the candidates, the question will get zero; if all the answers are correct, it will get 5 points; if there are no wrong options in the selected answers, but all the correct options are not selected, it will get 3 points. Therefore, we should pay attention to methods and strategies when doing multiple-choice questions.
Skills of answering multiple-choice questions in mathematics: pay clear attention to problems, such as wrong, possible, incorrect and certain choices. These keywords must be carefully read to avoid losing points. The simpler the question, the more you should look at it carefully. Choose the answer that you think is 100%. You would rather not choose the answer that you are not sure about than choose the wrong one.
Exclusion method: if you don't know the correct method, you can exclude some wrong questions of 100% before making a choice, so the success rate is at least 50%. Special value method: substitute a certain value and the answer is correct. This method not only saves the complicated calculation process, but also wins more examination time.
