If you don't pay and don't work hard, you will definitely get nothing. But that doesn't mean that hard work will necessarily reward. While working hard, you should also pay attention to the right direction. In this way, you will not only have a harvest, but also a larger harvest. In fact, there are many middle school students, and they also put in a lot of time. They are also busy every day, busy completing the homework assigned by the teacher, and brushing all kinds of materials bought by their parents. But why is it that their grades are improving slowly, or that the results are not obvious?Let's listen to this teacher's analysis. (The following materials are from the Internet).
He said, basic students, middle school students, the right direction of your efforts is not to increase the amount of questions, but to do the questions thoroughly. Not only should it not be increased, but it should also be reduced. Let's give you an example, tell you two underlying logic, and then talk about two basic steps, and you will double the efficiency of doing questions. 
The year in the following options is not a leap year?a.Year 1800;b.1896;c.Year 2000;d2024. I believe that many people can see the answer to this question at a glance. If you can easily pick the answer, then this question is skipped. So what can you do right?Will you take the test like this next time?If you do this question correctly, it does not mean that you have mastered all the knowledge points of this question. Do you know all the knowledge points related to leap years?How to determine leap years: divide by 4 If it is divisible, it means that it is a leap year, but this is only the first half of the sentence. There is also a sentence to add, there is no leap in 100 years, and there is an leap in 400 years. This has to do with the divisibility of 4, to see if the last two digits are multiples of 4, and if so, it is a leap year. Of course, if the last two digits end of 00, then this number must be an integer multiple of 400 to be a leap year. It may give you a condition next time that the number of days in each quarter of a year is equal to that of the first quarter;Or something like how many birthdays Xiao Ming has had, but his uncle has had fewer birthdays than him. When you see this, do you immediately think that it may be related to leap years, and do you know which specific knowledge point it is related to?
So there are two underlying logics, the first is that the content you learn is knowledge, and the purpose of doing questions is to help you master and understand knowledge. Have you memorized the knowledge before doing the questions?Did you feel the deeper meaning of knowledge when you did the questions?After completing the questions, do you have the ability to confirm that the knowledge is in place?If not, the question won't work. 
Second, knowledge is limited, but the question is infinite, the question sea, the question sea, this is what it means. You have to count on learning the knowledge thoroughly by increasing the amount of questions you do, and you have to be exhausted. It's like a theory test for adults taking a driver's license. There are usually two ways to approach an exam. One is to memorize all the content first, and then do two or three mock tests (there will be some changes in the questions each time). The other comes up to do the question directly, of course, most people's grades at this time are relatively low, and 60 points can be considered high. So they can do mock exams all the time, and slowly, the scores come up.
The former is to learn the knowledge points first, full coverage, no fear of any questions, soldiers will block, water will flood. The latter is to increase the probability of encountering the same question by constantly doing the questions, and the more the same questions are encountered, the easier it is to get a high score in the exam. Which of these two ways do you think is better?The decision you have to do is not to increase your knowledge points directly by doing questions. And if you learn the knowledge badly, then the questions in the back can be done or not, and the plenary will be over. Because no matter what the following questions look like, you must use your limited knowledge to solve their underlying logic. 
If you can win all the knowledge points related to a question and confirm that they are in place, it means that the knowledge has been mastered. After that, it doesn't matter whether you choose to fill in the blanks, or answer the questions. No matter how much it examines it, it is still an examination of this knowledge. So if you look at a limited number of questions, you can grasp all the knowledge. Once you have mastered the knowledge, do you need to increase the amount of questions?On the other hand, the reason why you didn't do well after studying for a long time is not because you have a problem increasing the amount of questions, but because you have not done the questions thoroughly.
