There are many knowledge points in high school and many extensions. Can't relax. I did well in math in high school. Most of them are sloppy. My method is also very simple. I hope it helps you.

First of all, I always know the concept of books very well and fully understand them.

Second, I attach great importance to the examples in the book and have been studying them. Examples show the basic application methods and problem-solving ideas. Mainly look at ideas and methods. If you have the conditions, you can go to a remedial class to expand your language thinking. That's how I got here. See M//S M//s/ 1.html.

Third, do exercises. The practice of mathematical exercises is essential. But don't do everything, you will do a lot of useless work. Do questions in books, college entrance examination questions, etc. , are generally standardized. From easy to difficult.

Fourth, learn to think independently. Don't ask others everything. Don't always look at the answers, it will form dependence. It is important to think more and have your own thinking system. And exercise your brain.

Fifth, there will be no internship there.

Conduct special exercises for questions, knowledge points and places where you can't. Now there is a word called deliberate practice. That's what I said.
