You can't change your talent. Diligence depends on your attitude, such as doing more problems. But the most important thing is the learning method. With good learning methods, you can greatly improve your math scores.
Learning math, books are completely useless. It is more important to listen to the teacher, which is more important than how many books you read and how many questions you do. For example, I often copy my homework in math, but my grades have always been among the best. Listening to lectures should not only listen to knowledge points, but also think about some essential problems on this knowledge point. You must have a knowledge network in your mind and have a layered sense of knowledge.
It is necessary to be clear about the types of mathematics in the senior high school entrance examination, taking everything and knowing nothing. However, it is obviously not the best policy to break through the questions in the senior high school entrance examination one by one. This kind of thing is only suitable for general review. More importantly, you need to have your own core idea of solving problems and never give up thinking. For example, in geometry, to find the law, think before you do it. If you want to know one thing, you must know the thinking mode of one thing, and you must have a chain to prove the conclusion step by step, and constantly understand the essence from simple questions to difficult questions, rather than being limited to this question.
