How to solve the problem of mathematics in my 20 12 senior high school entrance examination?
If you can guarantee all the problems except the finale. . Then I suggest not to go to the training class. The effect of her self-study will be better than any training class. . Let's talk about the mid-term exam questions in recent years, which come from Guangzhou and nearby cities. . Circle the content of the finale, then read the book first, and then read the test paper in combination with the book (in fact, you can find that the topic or all the solutions to the problem come from the textbook, which I think everyone will sum up a little differently, and most people may only do the problem, ignoring the systematization and generalization of the problem or the steps and methods to solve the problem, so that a large class of problems can be dealt with in the summary). . . . Find a good tutorial book (not a question bank) after you finish it. . Refer to see if your summary is useful, if there are any problems, and if there is anything that needs improvement. . Textbooks are the mainstay, real questions are the mainstay, and counseling books are only 1. . For the finale, generally speaking, we will not simply test one content, but two or three contents together, but read the book carefully, pay attention to the topic, and then think deeply. . In fact, there are not many things that can be United. . . And then the ending is turtles in a jar. .

If you haven't been able to ensure that all the previous questions are correct, you must first ensure that they are all correct. . Why? Because these are basic questions. Choose, fill in the blanks and answer all the big questions correctly. . Especially for multiple-choice questions and fill-in-the-blank questions, 1 is 5 points, which is very expensive. . If you want to get good grades, you must ensure that everything is all right, and the senior high school entrance examination and the college entrance examination are the same. . . That's what the teacher asked us before. .

As for the training class or something. . I think my daughter's grades are definitely not bad if the landlord can ask such a question. Personally, I really don't think it is necessary to go to the training class, for fear that the training class will waste her time. Ask my teacher to see if there is anything wrong with her efforts. If not, let her summarize herself. . Of course, if you can ask people who have experienced these things, it will save a lot of time, because it is a waste of time to bring people the fruits of their labor. . Here, I would like to share with you some points that I summed up when I tutored two senior three students in geometry during the winter vacation:

1. Solve the problem of geometric proof: first memorize the theorems and see what the question asks (mostly proof and judgment), then think about how many direct theorems there are, choose the best one in 1, and then see what conditions the question already has and what is the difference. Then treat these poor conditions as a small proof problem, and continue to repeat the above steps until all the conditions are directly found on the problem. Then the idea is ok. Just write those things from the back to the front when you answer the questions. . . Generally speaking, there are two key steps: selecting principles and finding conditions. . . . Generally speaking, you can't only prove 1 time, but most of them are ok after 2~3 times, that is, you can't directly prove what you want in a topic, but you must prove 1~2 things first, and these are the conditions for you to finally prove the topic. . .

2. Solve the trajectory problem and find the analytical equation: refer to the two required cycles and the example in Equation 4. . I summed up the textbook as "representation method", which is divided into three steps: finding relationships, listing representatives and solving equations. . . Remember these nine words, and you will naturally understand them after reading the textbook. . . Later, I asked those two students to apply this method to the elective conic section I didn't talk about. . I don't want to tell them, they will do it themselves. The analytical equations of straight lines, circles and conic curves are definitely the big questions behind the college entrance examination. . So I think this should be very suitable for all the problems of solving analytical equations. .

I share these two methods with you because of the proof of triangle and circle. Analytic equation is definitely a big question in the senior high school entrance examination. .

Back to your question, training class, I don't recommend it, why? Because students have been to most tutoring institutions in Guangzhou as teachers, they know other inside information. So I don't want to waste your daughter's precious time. . . On the contrary, if you have real in-service teachers around you (be sure to be true, there are too many so-called in-service teachers in key middle schools now! You can ask for his teacher's ID number, and you'll know if it's true or not when you look it up), or a teacher or college student who made it up by a familiar person and got good grades. . Then I think it is still reliable. .
