Junior high school mathematics problems
Son, I am a junior this year. Although I mean seniority, I'd better tell the truth.

I am a candidate from Yunnan. I got a 580 in the college entrance examination the year before last. In terms of proficiency, I can only get 550, and 30 points is no problem. We scored 500 points in grade three, and finally I was 80 points higher than grade three, and went to a good school of 2 1 1. If I didn't get this question, I think I'm studying in Dayun now.

What's the problem? To put it bluntly, you are not absolutely sure about a question, and it is nothing special to guess an answer. The question is only useful if you understand the topic and know what to do, but you can't work out the specific answer. If you don't know anything, it is very impossible to do it right.

Before, a classmate asked me why I was always so mysterious. Isn't it obvious? I'll be lucky if I'm completely wrong. If I know all the methods, I will be fooled when I calculate, which means I can be fooled as long as I have enough time.

Level and experience are the key to improve the correct rate of Mongolian questions. Your level is not up to that point, you can only be blind, and it is unlikely to be right.

A friend of mine finished 12 multiple-choice questions in 20 minutes in the math exam and got 10 right. Not because he does it quickly, but basically because of ignorance. But he won the second prize in the national mathematics competition, and the level is there. I want to learn from him but I can't even learn the questions!

With the improvement of learning level, the correct rate of questions will come up. What is not level is luck, and luck can't be good every time.

But the skill of fuzzy problems in math problems is substitution and exclusion. According to some theorems, we can infer the possible range of the answer, eliminate the wrong answer, and then substitute the remaining options for calculation, which can save time.

For example, a math problem, if you know from experience that the answer must be positive, you can exclude both negative numbers and zeros, bring positive numbers in and check, and the answer will come out at once.

You can do the same for physics problems. You know the approximate range of a certain force, so you can directly exclude the options outside the range.

Chemistry questions can't be so vague. Only by doing more questions and doing more questions, you will naturally guess the answer.

Will the choice of China people be fooled? I haven't heard of it. Only poetry appreciation and reading questions can have answering skills in Chinese. Ask your classmates. I can't type clearly here. Their methods can't be wrong.

We all know English questions, and choosing the words we have learned recently is generally correct, haha.

Biology problem, can this be fooled? This basically depends on endorsement. You can recite it well.

Political geography history, because I am a science student, I really don't know how to do it, please forgive me ~ ~

PS: Don't believe that God is talking nonsense. He can do it right in junior high school, which is not a skill. I was too lazy to do it in junior high school. I didn't start practicing until I went to high school. I really don't know how to do it until I learn to get it.

If you have time, it is ok to study hard. Anyway, you don't have much to do in junior high school. What can you do without learning, right _

Relax, we understand your feelings, and you think it's ridiculous to learn the "garbage" in these textbooks. The exam will accompany us all our lives. You must get used to it, son.

By the way, my brother has already taken a job and has to take an exam, and it's the 22nd. He really ... takes the exam forever. None of us can escape.
