How to improve math scores quickly?
Can't crash, can only rely on the usual accumulation and review.

First, firmly grasp the basic concepts; Second, master basic methods and common skills; Third, do a lot of questions on this basis. I also think what the teacher said is very reasonable. For example, how many formulas can you think of when you see sinx and cosx? The sum of squares is one or two times the angle, which is omnipotent. . . Can everyone remember? There are all kinds of problems. Let's just say that at that time, when it came to test sites, N methods came to mind. However, some people may not be able to think of any way. This is the difference. I suggest you start with the basic concepts, which can improve your level. In addition, I suggest that you classify the types of questions, that is, when you are writing a book, what you think of after reading the book is not the messy topics, but the methods. One kind, especially effective in a series of questions ~ ~

In addition, it is very important to do the problem, just make sure one sentence ~ and ask the teacher more in the usual practice, and make sure that you can't.

In fact, to tell the truth, high school mathematics is very easy to learn. I think you can do a few questions. If you do more, you will find that the questions are all of the same type. If you want to start from the basics, I suggest you read a book called Shan Zhi Scan. The book made by my boyfriend has consolidated the foundation and won't make mistakes again because of carelessness. You have to "do a lot of problems" ~ ~ ~ It will be boring at first, but if you break through that bottleneck, I believe you will enjoy it. In fact, I am very happy as soon as I do math, because you will gradually find that many formulas have worked out a very clever number, how wonderful! And because of a wonderful method (this method is remembered), it is a great sense of accomplishment to work out a seemingly complicated problem!

As BY27 said, just look at the formula before the exam, and there is no significant effect in doing the problem, just look at the basic concepts. So you know how important the basic concepts are. The process of laying the foundation is very important. You are still a sophomore. You have enough time. Work hard ~ ~

As for the time for studying mathematics, it is enough to set aside three days a week and concentrate on studying mathematics for two hours at a time. Make a summary on weekends and often take out the wrong questions. Many people say they took the wrong book. I don't think the average person can persist. Just flip through it often. Do what is wrong, and never perfunctory, because it is a sophomore. When I was in the third year of high school, I basically wrote math every day, doing the green channel and reviewing the book all the time, and then the school paper. Cultivate your sense of touch, and you will understand that if you don't do math for two days, you will make many careless mistakes, and you will feel strange if you can't figure out a way to look at the problem.
