0335 My math swings at 100~ 120. I am a science student, and the big problem is a problem with a large amount of calculation. It's 20:58:27. Should I spend a lot of time practicing such questions?
A: There is no need to spend too much time, just make sure that every question is done carefully and try to avoid past mistakes.
Hello teacher 3 192, I am a science major, and my math score is over 80 points, but our teacher has mastered the last three questions this month. Should I follow the teacher? 20:52:54
A: It is very important to listen to the teacher's class. In fact, the last three big questions are actually composed of many small questions. The teacher's analysis and emphasis are still useful to you. Of course, you can give up when you practice.
3494 What if you don't know how to do the problem 20:52:38
Answer: read, listen to the teacher's class and think about what the teacher said.
9276 What to do about right and wrong questions 20:52: 12
Answer: We must make mistakes seriously, and high-quality mistakes will get twice the result with half the effort.
What is the trend of 295 1 solid geometry examination? My solid foundation is not good. Can I raise one question every day? 20:48:0 1
A: The questions are stable in form and moderate in difficulty, and mathematics pays attention to the coherence of thinking. I suggest you spend a weekend concentrating.
2395 has done a lot of solid geometry problems, but what should I do if it is still not good? Only the first question will be asked in every exam. For example, the theorem of three perpendicular lines cannot be seen in complex graphics; And I don't know how to make auxiliary lines. What should I do? 20:43:57
A: There is no difference between doing a problem without summarizing it and doing one. Take out the three-dimensional path you have made in the past and look at it again. You will sum up a lot of ideas for making auxiliary lines, provided that you are proficient in the theorems in the book.
7878, my math score is average. Is it useful to do all the examples in five high school books at 20:45:07 now?
A: It is certainly useful, but when you do it, you should ask more why and compare it before and after.
4 128 teacher, can you talk about this year's application? This is weak! ! Thank you. 20:44:05
A: On the one hand, Beijing's application questions in recent years are mainly related to probability; On the other hand, it is mainly put forward from the background of practical problems that it is not as difficult to establish practical mathematical models as foreign papers, such as 19 in 2007 and 13 in blank.
2579 prove that the straight line is parallel to the plane until it is perpendicular to the normal vector? 20:42:50
A: Judging from the explanation of this year's college entrance examination, the proof in this respect is not clear enough, because this idea has been clearly given in the materials. I suggest you adopt the conventional method. Of course, it is really impossible. You can also use this.
Hello, teacher 897 1, can I focus on Beijing when I am doing "May 3rd"? If I need to do some foreign questions, then you can suggest which provinces I should do more. Thank you. 20:4 1:20.

186 1 my usual exam 1 10 to 125. I found that I am not good at time allocation, and there are many careless mistakes ... excuse me, teacher. How should I allocate the time for filling in the blanks and answering questions at 20:40:28?
A: According to your grades, I suggest you try to finish the first 14 question within 35-45 minutes. In this process, you should give up thinking about the problem for more than 3 minutes and take over the basic points of solving the problem. At this time, your mind will relax.
Hello, teacher 1794, my knowledge is not very solid. What if something goes wrong in some places? Some places learn very well, and some places can't learn at all. ) It's almost the same. I'm in a hurry! 20:39:49
Answer: Analyze the nature of your fault. If you don't know anything, then give up. If you are ambiguous, try harder. Although there is not much time, it must take some time.
8589 I want to ask the teacher how to give questions in the exam. Basically I won't touch the last two questions ~ 20:39:47.
Answer: Do it in order from the beginning. Fill in the blanks and choose the topic. If you want to be philosophical for more than 3 minutes, let it go. If the big question is invalid for more than 5 minutes, let it go. Do your best, and then come back and think about it.

Teacher 9782, I want to ask what I should do if I don't do the problem now, but I always make mistakes, whether it's miscalculation or copying.
A: Adjust the examination mentality.
Where should the focus of 89 15 science mathematics be? Should we practice the examination questions of some provinces and cities with similar propositions to Beijing in 2007? 20:39:09
A: You can work harder on your weak chapters before you die, and then work harder on the chapters you have learned well after you die.
090 1 I am an elite student. Now I have finished the simulation questions of each district last year, but the results are unstable. I don't know what else to do, and I am afraid of making mistakes in Beijing. I'm a little overwhelmed. 20:39:03.
Answer: Do the exercises assigned by the teacher.
Every time I finish the Beijing simulation problem, I will write down the knowledge points I can't, but I can't do the same kind of problems. How can we remember them deeply? 20:38:54
A: Mathematics can't rely on memory, but on thinking.
Hello, 2086 Presiding Teacher, my math is always hovering between 1 10 and 120, but there are always choices or mistakes in filling in the blanks, and there are always some minor problems. How to break through? 20:38:54
A: Accumulate the mistakes and correct them one by one, and you will have a breakthrough.
Hello, teacher 6 198, I can't do the monotonicity of functions and some problems of the combination of numbers and shapes well. I don't know how to do it. 20:38:46.
A: First of all, correct it. The combination of numbers and shapes is a way to solve the problem. Listen to the analysis of old problems and carefully study the origin of each problem.
7509 ! ! ! ! ! ……! ! I heard from a researcher that typical problems should be done at present, but I am not good at summing up. What should I do? ? 20:38:46
A: The reference sample questions in the exam instructions are the best reference.
666 1 w was handed in and suffered heavy losses! Excuse me, teacher, how to improve the speed of answering questions on the premise of ensuring the correct rate? 20:38:38
Answer: First, ensure the correct rate. The improvement of speed is directly proportional to the proficiency of thinking, and it takes time to master anything. Never forget the desire for success.
666 1 w my math foundation is good, and the speed and accuracy of doing problems are ok at ordinary times, but I am too cautious when I encounter large-scale exams, and the previous basic problems take a lot of time, so I have never seen the last two 20:38:36.
A: Relax and believe in yourself.
Hello, teacher 3023. I have been at the top of my class in math in Grade One and Grade Two, but I failed every exam when I entered Grade Three. Feeling can't find feeling, but mathematics has always been a strong point. Can I improve it again? 20:38:24.
A: Yes, you can enter a bottle of learning expectations, adjust your persistence and give up your mentality. Don't compare the present with the past.
Hello, 009 1 teacher, I am now 1 12. What should I do to further improve? Do a lot of questions, or just follow the school teacher? How many kinds of conic problems are there? 20:38: 18
A: Read the questions you have done with the teacher again, and you will gain more than doing many new questions. The thinning of the same conic has 50 knowledge points, plus straight lines. You can calculate how many classes there are by arranging components.
5000 has some complicated problems. Should we give detailed answers when practicing at ordinary times, or should we look at more common solutions? If you want to test 140, how should you review? Thank you! 20:37:54
A: Think for yourself first, and then look at the answer. The purpose of reading the answer is not to understand how others do it, but to find the loopholes in their own thinking. Because everyone thinks that heat is their own thinking.
Teacher 9782, I want to ask what I'm doing now. It's not that I'm doing something wrong, but that I've been doing something wrong, either miscalculating or copying it wrong. What should I do 20:37:3 1?
A: As for the vector part, although vector and quantity are completely different issues, from the perspective of operation formula, there are not many similarities. We just need to master the differences.
08 15 hello, Mr. Chairman! I am a senior three student, and many formulas such as trigonometric function and vector can't be remembered or confused. How should I overcome them? 20:36:47
A: The formulas of trigonometric functions are all regular. As long as you work hard, there is no problem. The sum and difference of trigonometric functions, sum and difference algebra, universal formulas and derivative formulas of some basic formulas are all teachers' supplements, so there is no need to remember them. I mainly remember three identical basic relations, and seven groups of inductive formulas are just one sentence: "Singular changes are the same, but different signs are limited." Just remember the difference between the two angles and the heat of the two angles.
You can learn the basics of 9488, but you can't do problems. You can't do it when the teacher is talking. Don't talk about yourself. What's the problem? What shall we do 20:36:3 1
Answer: Be sure to warm up before the teacher speaks. After listening to the teacher's words, compare them and find out the shortcomings of your own thinking. It is important to reflect after listening to the teacher.
