First of all, I think it varies from person to person whether to do more math problems. For children with good foundation, flexible brain, good acceptance and good test scores, it is enough to do the exercises in moderation, and the exercises given to them must go beyond the conventional questions in order to improve their grades. Then you can use your free time to develop your child's other abilities. For children in the opposite situation, we must constantly practice proficiency by doing more questions, and improve the response ability and the correct rate and speed of doing questions.

Secondly, how to do more questions? Don't brush the questions blindly, choose the questions suitable for children's practice according to their mastery. Then in the process of doing the questions, we should constantly analyze and summarize, especially pay attention to the wrong questions. All the wrong questions in the exercise should be consolidated until they can be done correctly in one go independently. Then in future exercises, children will encounter the same type or variant questions, so that they can answer them flexibly and correctly.

Finally, pay attention to periodicity when doing problems. Any study should be gradual and persistent. You must not do it for five hours and rest for a week. Instead, we should make a study plan for a certain time every day to ensure the continuity of study progress.

In mathematics, many people say that we should do more problems. Only in this way can your grades be improved. In my opinion, it varies from person to person. For those very smart students, they can do one kind of problems and know another kind of problems, so they don't have to immerse themselves in the sea tactics all the time.

For those students who study hard, sometimes they will forget the questions in a few days. In this way, the tactics of questioning about the sea are better, and every time you do it, your memory will deepen. This is a good method.

For me personally. Need more brains. My cousin doesn't like to do problems in high school. He only finished one book, not many brush questions. Is to find out every problem thoroughly. The final college entrance examination score 142.

And a number of schools such as Hengshui and Wuyi Middle School. They are all sea tactics, and a question will make students do it several times. So I think it varies from person to person.

To sum up, if you don't consider the time cost, it is still beneficial to do so many questions. But in order to save time, so many questions should be done with skills and methods.
