Mathematics multiple-choice questions and fill-in-the-blank questions in the college entrance examination;
It takes about 40 minutes to complete the selection of fill-in-the-blank content. When doing multiple-choice questions and fill-in-the-blank questions, the average answer time for each question is about 3 minutes, and the previous easy questions are answered within 1 minute. Because there is basically no time to go back and check, we should try to finish the test questions at once.
Mathematics solution of college entrance examination:
The average answer time of each basic question is about 10 minute when the college entrance examination is a big math question. Students with different mathematical foundations in the college entrance examination have different feelings about the difficulty of the test questions. Students who have a solid foundation in mathematics in the college entrance examination can attack the last few big questions if they answer the questions smoothly and have plenty of time.
Unexpected situation of mathematics in college entrance examination:
Many students will have a short brain blank when they do math problems in the college entrance examination because they are nervous. When they find simple problems, if they can't solve them themselves, they will be more nervous, and then they will fall into an endless cycle of tension, inability to solve problems and more tension. You should put down the problem you have solved for a long time and move on to the next one.
Analysis of the difficulties in senior high school mathematics;
Function and image: Function plays a very important role in completing high school mathematics study and preparing for college entrance examination, but the definition, attributes, image and inverse function of function may be more complicated and difficult for some students.
Limit and derivative: Limit and derivative are two difficult contents in high school mathematics, which require students to master some knowledge of mathematical analysis, including derivative law, mixed operation law, monotonicity and so on. , but also need to understand complex functions and other parts.
Solving equations and inequalities: Solving equations and inequalities is one of the basic contents of high school mathematics, but solving general equations and inequalities usually requires good knowledge of mathematical culture and understanding and mastering problem-solving methods.
Plane vector and solid geometry: solid geometry is a difficult part of high school mathematics, including vector coordinate representation, vector linear operation, plane vector's * * line, parallel and vertical relationship, triangle area, cosine theorem and so on. It needs to master some geometric transformation methods, involving complex mathematical knowledge.
