There are many people who really talk about mathematical methods, and there is not much nonsense. Everyone knows the general method, which is only half a year. Nine times out of ten, your 1 10 situation is a difficult problem, and there is no way. Then you have to sum up the wrong questions, practice more, and pay attention to doing anything right, so as to improve the correct rate. You can't be simple and perfunctory, but form good habits so that you won't be late. Of course, it is really impossible. There is a way. For example, Fanny, my roommate scored more than 70 in math in the college entrance examination, but both Chinese and English scored more than 130, and the comprehensive management was close to 280. Of course, I'm not saying I don't work hard, but everything is dispensable. Don't go all the way to the end.
