Brushing questions is not absolutely useful. Depends on who you're targeting. It is very useful for students with good foundation to brush the questions. After brushing the questions, they can know where they are lacking and where they need to be further supplemented and improved. For some students with weak foundation, it is not necessarily useful to brush the questions because the foundation is not solid enough.

Is it useful to brush the math questions in senior high school? It is very necessary to do a lot of problems. You have to know a truth: the results of mathematics are all from a lot of practice, but the correct method of doing problems will really have an effect. You must choose the questions carefully and summarize the rules after you finish. It is best to copy down the wrong questions for final consolidation.

Many people are crazy to do more problems in the wrong way. After making a mistake, take another look at the correct answer and continue to brush the questions. This is not obvious, because it is not correcting mistakes, but changing the answer again, and there is no real intention of thinking and reflection. The next time you encounter a similar problem or even the original question, you may still make a mistake, so brushing a big question will have no effect.

How to improve math scores Many high school students have poor math scores because they don't concentrate in class, which leads to not doing problems after class. After a long time, it is difficult to concentrate in math class, and their math scores are getting worse and worse.

Therefore, if high school students want to improve their math scores, they must concentrate on listening in class. Teachers should take notes in the detailed problem-solving process of the contents that are not in the lecture book or classic examples, so as not to understand them in class and find them when they want to review.
