In fact, the key to mathematics is to understand and master formulas. There is not much content in high school mathematics, but most people only know rote formulas and methods. In fact, you can make great progress when you try to infer and understand them yourself.

In addition, the strength is not accumulated by doing a lot of questions, but by knowing every question you have done, especially by missing it, thinking more, asking more questions, summing up more, getting a wrong book or summarizing methods and points, and recording the problems and experiences that need to be read repeatedly. Like memorizing words in English, math problems need repeated processes.

In addition, those difficult problems need some skill and thinking. You must first have the confidence to explore for yourself. If you really can't, just look at the answers first, memorize their skills, and then do it yourself in a few days. Especially the classic questions must be copied down, whether it is required by the outline or not. Some questions are really an art, and they are also fun to do. "I am easy to change people, I am careless, I am difficult, and I am not afraid of difficulties." The education of childhood teachers is actually very reasonable.

Finally, you must have confidence and interest. Math methods in senior high school are very limited. As long as you are good at summing up, seeking quality instead of quantity, and understanding without reciting, you will certainly make progress.

These are just some of my personal feelings, and I hope I can help you.
