Mathematical scoring strategies of different scores in college entrance examination sprint: 1 10 to 130.
The basic score is about 1 10. If we want to further improve it to around 130, we must make a special breakthrough.
(1) Multiple choice questions: The difficulty should be controlled in the middle range, such as the difficulty of the last two multiple choice questions in the college entrance examination. Mainly concerned with functions, derivative functions, conic curves and series. Chapters with time to expand: mean inequality, vector, oblique triangle, solid geometry, trigonometric function and so on.
(2) Conic curve and derivative function: the difficulty is controlled in the difficulty of the college entrance examination. It is difficult to deal with the expression in the calculation of general conic curve: how to deal with this formula, how to deal with it? After doing the problem, you need to sum up more and try to figure it out. It is difficult to derive the derivative function. When you need to practice, you should sum up more, find out what are the similarities and differences between these topics, how to think, and whether you can use this method and ideas to solve problems in the future. This process needs trial and error.
90 to 1 10.
If your current score is about 90, it is estimated that your score should be like this: 7-8 multiple-choice questions, 3-4 fill-in-the-blank questions, the trigonometric function and probability of the first four big questions are relatively simple, and it is easy to get points, and the series and solid geometry are a little difficult, so it is estimated that you can get the first question, about 36 points, and the next 20,21questions will get a little point.
Special Breakthroughs: Breakthroughs in the first four problems, such as trigonometric function and trigonometric solution.
Preparation of basic knowledge points: induced angle formula, basic relationship of trigonometric function with the same angle, double angle formula, sine and cosine theorem, basic formula of trigonometric function, etc.
Preparation of basic methods: Generally speaking, the general idea of trigonometric identity transformation is that the auxiliary angle formula is needed to find the maximum value, monotonicity, image, symmetry and period of trigonometric function, and the order should be reduced before.
Solution of oblique triangle: for example
For the linear formula (fraction, equation) of "edge"-sine theorem comes to mind first.
It is known that the sides of the three internal angles A, B and C of △ABC are A, B, C, AsinB+bcos2A=a, which is equal to ().
Question exercise: choose some questions with the same difficulty as the college entrance examination, and the number of questions is 10 to 12. Be sure to sum up and combine the problem-solving methods.
Then there are probability, solid geometry and sequence method. On the basis of the usual comprehensive test paper, observe which plate and knowledge point have problems, and review them specially, so that you can get high marks when you choose fill-in-the-blank questions.
There is a comprehensive math exam at least once a week, which is as difficult as the college entrance examination. Review what problems you find, so that you can slowly make up all your loopholes.
60 to 90 points
If your score is only about 60, it is estimated that your score is like this: 5-6 multiple-choice questions, 1-2 fill-in-the-blank questions. The first four big questions, the probability estimate can get points, and the rest can get the first quiz, almost 60 points.
Only 60 points, indicating that the foundation is weak. It is basically impossible to review all the courses from Grade One to Grade Three in an instant. What should I do?
Audit by department:
Trigonometric functions and triangular solutions:
Knowledge points are reviewed by students themselves. If there are problems with some questions under some knowledge points, the review progress should be slowed down. For example, the formula of induced angle is difficult, and a breakthrough can be quickly remedied for this knowledge point. During this period, you need to do a certain amount of questions in order to use knowledge points quickly and flexibly in a short time (after all, the college entrance examination mainly examines the flexible use of knowledge points).
Probability:
Review the targeted knowledge points and test sites (the angle of test sites in this chapter is obvious): three sampling, stem and leaf diagram, histogram for median, average and mode, classical probability and geometric probability solution. This is the main test center for liberal arts. On this basis, science includes random event distribution, independent events, mean value, variance and so on. Targeted exercises and breakthroughs can get full marks.
Solid geometry:
Three views, volume and surface area (the three can be reviewed together). The positional relationship between points, lines and surfaces (lines are parallel to surfaces and lines are perpendicular to surfaces, which can be reviewed separately). The main explanation methods, such as: the parallelism between a straight line and a plane can be proved by the parallelism of the plane. The liberal arts mainly examines these. When studying dihedral angle in science, you can learn the method of finding dihedral angle, but many students choose to build departments to do it. The other is practice, which requires a certain amount of questions and more summaries.
Series:
The knowledge points of arithmetic and geometric series, the practice of questions under knowledge points, the solution of general formula and the solution of the first n terms can all be practiced on this basis. When you do the problem, you must combine the knowledge points and methods you have done and summarize more.
-After reviewing the above four sections, the purpose is to do well the top four questions in the college entrance examination and the previous multiple-choice questions.
The next step is to review the chapter on optional questions:
Function, vector, inequality, linear equation, circular equation, conic curve, derivative function. When reviewing, I mainly step on the test sites, such as inequalities. Multiple-choice questions and fill-in-the-blank questions are generally easy to examine a basic inequality and linear programming, and linear programming mainly examines those questions.
When reviewing the derivative function of conic curve, try to do the first question in the college entrance examination, and find the trajectory equation of conic curve, the maximum value, extreme value and monotonicity of derivative function, especially the monotonicity of classification discussion.
In the last few days, the easiest thing to score is math. If you study a subject, you will have a chance to get more than ten points, which is incomparable to other subjects. So, at the last minute, see which stage you belong to, collect this article and review it against it!
