Secondly, how do you learn math well?
You should make it clear whether you are not thinking well in mathematics or not working hard. It's easy without hard work. Push yourself, even once. After trying the sweetness of getting high marks in mathematics, you will be eager for that kind of happiness and continue to work hard. If the thinking ability is not good, then start from the foundation. Remember formulas, theorems and fixed methods, put the meeting in the first place in every exam, and be careful to make 100% correct. When you do this, you have achieved 60%-70% results. The rest depends on oneself to brush more questions at ordinary times, sum up methods, and draw inferences. The advantages of brushing more questions definitely outweigh the disadvantages. The key point is to summarize, reflect, summarize and study repeatedly, otherwise, no matter how many questions you have, you can't make any progress. In addition, pay attention to brushing the questions. There is no need to brush what we have firmly mastered. The focus is on the questions that can't be brushed and the questions that can't master the methods, that is, the knowledge points can't and the methods can't. These are all possible. To do this, it is hard not to improve mathematics. Believe in yourself and don't be afraid of math.
Finally, if you haven't chosen science for a long time and feel that it is not suitable for you, you can choose to switch to liberal arts. But if you have been divided into subjects for a long time, it is not recommended to transfer to liberal arts. This is because you have fallen behind a lot of liberal arts knowledge, which is difficult to make up for under the fast-paced study in high school. Since you have chosen science, study hard and come on!
