Speed of answer: 26-27 questions in the senior high school entrance examination mathematics paper, the examination time is two hours, with an average of more than 4.5 minutes per question. In order to leave enough time for solving middle and high-level questions, each multiple-choice question and fill-in-the-blank question should be solved within two to three minutes. If these questions take too long, even if they are done correctly, they are "potential loss of points" or "implied loss of points" 6, based on the middle and lower topics, strive for a high level of homework at ordinary times, are completed according to all topics, but the senior high school entrance examination is not, only a few students can hand in full marks, because time and the difficulty of individual topics do not allow most students to finish all the topics correctly, so we should base ourselves on the middle and lower topics on the answer sheet. The middle and lower level questions usually account for more than 80% of the whole paper, which is the main composition of the test questions and the main source of candidates' scores. Students can win these questions, which is actually a victory in mathematics. With the mentality of winning, they will be more open to overcome high-level problems.
