I did well in math in junior high school and senior high school. Personally, I don't think there are any shortcuts, and I don't think I am smarter than others. Mainly diligence, the so-called heaven rewards diligence. To be more specific, preview before class and understand at least 50%. If you don't understand, keep your own questions and listen to the class with them. If you don't understand after class, ask the teacher after class. Then practice more after class, ask the teacher's advice, buy some after-school counseling books, and then do more exercises. As the saying goes, practice makes perfect, as is the case with many math problems. If you do more, you will find the law and summarize it yourself.
