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.

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.
