I don't think how to learn mathematics can be clearly stated in one sentence, but I can talk about it from my point of view. Let's talk about how it is usually done! According to your friend's specific situation, she should read more textbooks. Books are the most important thing. Generally speaking, as long as she explains the knowledge in the book clearly, no matter how the questioner tests her, she can cope. Why? You know, the exam is always like this, and its prototype is always the knowledge in books. No matter how difficult the topic is, we can break it down into several small problems, which basically come from books. Let her read, not let her read word by word, but carefully look at the important things in it, such as formulas, which will definitely pass (of course, more than one factor). For example, when I was in high school, I always focused on textbooks, so I got the first place in hundreds of exams throughout high school, more than 90% of the time. Now I teach a student who knows everything except that he can't remember the formula clearly. Because of this, it is difficult for him to get up in math. Later, I asked him to study hard and his grades really improved. Usually, you should do the questions in moderation, not too much, and certainly not too little. If you do less, you may not be familiar with doing the questions during the exam! Let's talk about the exam. First of all, it is a matter of time. For most people, it is normal that they don't have enough time to do math, so there are many times when she doesn't always think about how to finish the paper. My math teacher said before that it is wise to give up some questions and try to ensure the correctness of the finished questions, but this does not mean that she deliberately gave up some questions and did not do them, but deliberately checked them, depending on the specific situation. For example, when she thinks that she really can't work out a single topic, and there are many uncertain topics (not very difficult) before, then she can go ahead and check, don't take chances, and always think, "Maybe what I did before may be right." The previous one was more than five points. It's a pity to lose! Or she thinks that she has done a good job in the front, and there are still a certain number of problems (which she thinks can be done) that have not been done, so she should do the latter. After all, there are so many points behind! In addition, when making a fuss, we should try our best to pay attention to skills. Don't always be honest. 120 minutes. How do we do this? She should try to use some simple methods, which I think are very clear in many books. As long as she understands and appreciates beauty seriously, it is no problem to master those methods! Let's talk about some other problems, that is, when she is doing the problem, she tries not to think about other things, how many points she must get in this exam, and what bad results will there be if she doesn't do well in the exam. Anyway, in a word, concentrate when you do it! Pay close attention! One more thing I want to say, don't care too much about your usual grades. If you care too much, you may spend most of your energy. If you have such energy, you might as well spend it on your study, so the effect may be better. Believe in yourself, there is no need to worry, as long as you don't lose heart, you should be fine. I always think that there is no fixed method for learning, it depends on the specific situation, so I can't think of any good methods for others. It is very likely that she has a good method, but she just doesn't show it!
